Sample ENADE Engenharia Mecânica Practice Questions

Try these sample questions to test your ENADE Engenharia Mecânica exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to Brazilian Federal Law No. 6,496/1977 and the regulations established by CONFEA/CREA, what is the legal nature and primary purpose of the Technical Responsibility Note (Anotação de Responsabilidade Técnica - ART)?
A.It serves exclusively as a tax receipt that collects municipal service taxes (ISS) on engineering consultations.
B.It legally defines the contractual scope, identifies the professional and technical responsibility for the mechanical project or service, and constitutes the engineer's technical-professional collection (Acervo Técnico).
C.It is a mandatory operating license issued by the Ministry of Labor that certifies machine safety compliance prior to municipal inspection.
D.It functions as an insurance policy that automatically indemnifies third parties against mechanical failures without requiring proof of technical fault.
Explanation: Federal Law No. 6,496/1977 instituted the ART, which legally binds the mechanical engineer to the executed contract or technical study. It defines the boundaries of civil and ethical liability while forming the basis for the professional's Technical Collection Certificate (Certidão de Acervo Técnico - CAT) issued by CREA.
2Under CONFEA Resolution No. 1,002/2002 (Code of Professional Ethics for Engineering), how should a mechanical engineer act when pressured by an employer to sign technical drawings and commissioning reports for a pressure vessel that was designed without observing applicable safety factors?
A.Sign the documentation while registering a confidential internal memorandum that disclaims responsibility in case of catastrophic burst.
B.Delegate the signature to an engineering intern or non-registered mechanical technician to shield professional liability.
C.Refuse to sign or endorse the technical documentation, formally alert the contracting party to the hazards, and abstain from executing unsafe engineering acts.
D.Approve the documentation under the condition that hydrostatic pressure testing is waived to prevent plastic deformation.
Explanation: Resolution No. 1,002/2002 dictates that engineers must preserve human life, public safety, and ethical integrity above commercial or employer pressure. Endorsing defective or hazardous designs violates fundamental ethical duties and exposes the professional to ethical, civil, and criminal sanctions.
3Brazilian Regulatory Standard NR-12 (Safety in Machinery and Work Equipment) establishes safety architectures based on risk categories (ABNT NBR ISO 13849-1). Which characteristic specifically distinguishes a Category 4 safety circuit from lower categories?
A.A single component fault does not lead to the loss of the safety function, and the fault is detected at or before the next demand upon the safety function, or accumulation of undetected faults does not prevent safety action.
B.The system relies entirely on single-channel electromechanical relays with periodic manual calibration intervals.
C.Safety functions are integrated solely via software without hardware redundancy or positive-action electromechanical contacts.
D.The occurrence of a single electrical short-circuit immediately permits machine cycling if an optical sensor is illuminated.
Explanation: Category 4 (under NBR ISO 13849-1 / NR-12) provides the highest architectural reliability: safety functions are maintained despite single faults, and faults are detected before or at the next demand, preventing accumulation of latent faults from degrading safety performance.
4Regarding emergency stop devices on industrial mechanical presses governed by NR-12 and ABNT NBR ISO 13850, what operational requirement must be satisfied when an emergency stop button is actuated?
A.It must stop the hazardous motion through the fastest feasible method without creating additional hazards, and releasing the button actuator must not automatically restart the machine.
B.It must automatically reverse the stroke of the hydraulic ram to full top dead center at maximum operating speed.
C.It must de-energize the entire manufacturing plant substation, interrupting critical ventilation and illumination networks.
D.It must allow machine restart immediately upon releasing the mushroom push-button without requiring a secondary manual reset.
Explanation: According to NR-12 and ISO 13850, emergency stop devices must bring machinery to a controlled safe stop (Category 0 or 1 stop). Disengaging or resetting the actuator must merely reset the safety circuit; machine restart requires a deliberate, separate command from the primary control panel.
5A cylindrical compressed air receiver tank has an internal volume of $V = 4.0\text{ m}^3$ and operates at a maximum allowable working pressure of $P = 1.25\text{ MPa}$ ($12.5\text{ bar}$). Under Brazilian Regulatory Standard NR-13, what is its potential hazard category, knowing that air is classified as Fluid Group C (combustible/toxic fluids are Group A/B, inert/air are Group C/D)?
A.Category V, because compressed air is non-toxic and non-flammable regardless of the $P \cdot V$ product.
B.Category I, because the operating pressure exceeds $1.0\text{ MPa}$.
C.Category III, because the $P \cdot V$ product equals $5.0\text{ MPa}\cdot\text{m}^3$ (which is $\ge 2.5$ and $< 30$) and the fluid belongs to Group C.
D.Category II, because any pressure vessel with volume greater than $1.0\text{ m}^3$ is automatically classified in Category II.
Explanation: NR-13 categorizes pressure vessels based on the fluid group (air is Group C or D depending on toxicity/combustibility classification, specifically non-toxic/non-flammable standard gases) and the product $P \cdot V$ where $P$ is in MPa and $V$ is in $\text{m}^3$. Here $P \cdot V = 1.25 \times 4.0 = 5.0\text{ MPa}\cdot\text{m}^3$. For Group C fluid with $2.5 \le P \cdot V < 30$, the vessel falls squarely into Category III.
6Under NR-13, an industrial steam boiler must have specific mandatory instrumentation and safety devices before being authorized for continuous operation. Which set of items is strictly mandatory according to NR-13?
A.At least one pressure gauge visible to the operator, an automatic water level controller with two independent alarms, and at least two safety valves (or one for small category B boilers) calibrated to relieve at or below the MAWP (PMTA).
B.A bypass line that allows discharging unmetered superheated steam directly to the floor without safety relief valves.
C.Only a manual Bourdon gauge, with automatic cut-off sensors considered strictly optional.
D.A single rupture disc without any pressure gauge or safety valve.
Explanation: NR-13 explicitly mandates: (a) at least one calibrated pressure gauge displaying MAWP (PMTA), (b) redundant independent safety valves with adequate relieving capacity, (c) water level monitoring with automatic low-level interlock to cut fuel supply, and (d) an up-to-date safety logbook (Livro de Registro de Segurança).
7In the context of Life Cycle Assessment (LCA / ACV) for mechanical manufacturing processes governed by ABNT NBR ISO 14040/14044, what does the 'Cradle-to-Grave' (Berço ao Túmulo) system boundary encompass?
A.Only the electricity consumed during the final machining and assembly of the mechanical component.
B.All life stages from raw material extraction, processing, manufacturing, distribution, operational use, through to final disposal or recycling at end-of-life.
C.The duration of the product's commercial warranty provided by the original equipment manufacturer (OEM).
D.The transportation logistics exclusively between the regional steel mill and the machine shop.
Explanation: A 'Cradle-to-Grave' LCA evaluates the comprehensive environmental footprint of a product across its entire life cycle: raw material extraction (cradle), manufacturing, transportation, active service life, and ultimate decommissioning/disposal (grave), per ISO 14040.
8An industrial manufacturing facility implements an Energy Management System compliant with ISO 50001. When establishing the Energy Baseline (EnB) and Energy Performance Indicators (EnPI) for a plant with three compressed air systems, what is the primary technical objective?
A.To maximize total plant energy consumption so that utility tariffs can be negotiated at bulk discount tiers.
B.To establish a quantitative reference period against which energy efficiency improvements and specific energy consumption (e.g., $\text{kWh}/\text{Nm}^3$ of compressed air) can be systematically measured and verified.
C.To eliminate the need for preventive maintenance on compressors and pneumatic piping lines.
D.To replace all electric motor drives with non-condensing open steam turbines regardless of thermal balance.
Explanation: Under ISO 50001, the Energy Baseline (EnB) provides a quantified historical benchmark of energy use, and EnPIs (such as $\text{kWh}/\text{Nm}^3$ compressed air) enable engineers to track performance changes, assess energy conservation measures, and verify verifiable savings.
9In Brazil, the environmental licensing of industrial metallurgy and manufacturing plants is regulated by CONAMA Resolution No. 237/1997. What is the correct sequence of environmental licenses required from initial conception to industrial production?
A.Operating License (LO) $\rightarrow$ Installation License (LI) $\rightarrow$ Preliminary License (LP)
B.Preliminary License (LP) $\rightarrow$ Operating License (LO) $\rightarrow$ Installation License (LI)
C.Preliminary License (LP) $\rightarrow$ Installation License (LI) $\rightarrow$ Operating License (LO)
D.Installation License (LI) $\rightarrow$ Preliminary License (LP) $\rightarrow$ Environmental Closure License (LCA)
Explanation: Brazilian environmental law establishes a three-stage licensing process: 1) Preliminary License (Licença Prévia - LP) approving site location and environmental feasibility; 2) Installation License (Licença de Instalação - LI) authorizing plant construction; and 3) Operating License (Licença de Operação - LO) authorizing industrial operation after compliance verification.
10The Brazilian National Solid Waste Policy (PNRS - Federal Law No. 12,305/2010) mandates the implementation of reverse logistics (logística reversa) for specific post-consumer mechanical and electrical products. What is the fundamental principle of reverse logistics under this law?
A.Transferring 100% of waste management costs and recycling obligations exclusively to municipal public cleaning agencies.
B.A shared responsibility system among manufacturers, importers, distributors, and consumers to collect, return, and environmentally repurpose or dispose of products at the end of their life cycle.
C.Exporting all industrial machining swarf and spent lubricants to developing countries without domestic processing.
D.Prohibiting the reuse of any reconditioned metal components in mechanical assemblies.
Explanation: Federal Law No. 12,305/2010 defines reverse logistics as an economic and social development instrument characterized by a set of actions designed to facilitate the collection and return of solid waste to the business sector for reuse, recycling, or environmentally appropriate final disposal under shared responsibility.

ENADE Engenharia Mecânica Study Tips from Top Performers

1Read Portaria INEP nº 165 of 14 April 2026: it lists the 18 objetos de conhecimento that define the Componente Específico, and it replaced the pre-2026 guidance.
2Practise full thermodynamic cycle analysis with steam-table style data: Rankine efficiency including pump work, regenerative extraction fractions and refrigeration COP.
3Be quick with Mohr's circle in both directions, and know when Tresca, von Mises and brittle Coulomb-Mohr each apply — mixing brittle and ductile criteria is a common trap.
4Drill machine-element formulas you will not be given: Marin factors, Modified Goodman, Lewis bending stress, the Wahl factor and bearing L10 life exponents.
5Review NR-13 pressure-vessel categorisation by fluid group and the P·V product; it is the most frequently examined safety rule in this area.
6Work manufacturing calculations numerically: Chvorinov riser sizing, maximum rolling draft, Taylor tool life and IIW carbon equivalent.
7Do not neglect the 15-item Formação Geral block; it is not engineering-specific and draws on the transversal themes listed in Portaria INEP nº 154/2026.

Frequently Asked Questions

What is the official structure of the 2026 ENADE Engenharia Mecânica exam?

Under Edital INEP nº 61/2026 and Portaria INEP nº 165/2026, the paper runs for 4 hours and contains 46 items: 15 Formação Geral multiple-choice questions common to every course in the cycle, plus a Componente Específico of 30 multiple-choice questions and 1 discursive question. The 2026 sitting is on 29 November 2026.

Is there a pass mark for ENADE?

No. ENADE produces no individual pass or fail. It is a mandatory curricular component, so a graduating student who is registered and fails to sit it cannot graduate, but the scores are used to build the course's Conceito Enade on a 1 to 5 scale and feed the CPC and IGC quality indicators for the programme and institution.

Who has to sit ENADE Engenharia Mecânica?

Graduating (concluinte) students of Bacharelado em Engenharia Mecânica whose institution registers them through the Sistema Enade. Entering (ingressante) students are no longer required to sit the paper but must complete the Questionário do Estudante Ingressante to stay in good standing.

Is there a fee to take ENADE?

No. ENADE is free for students. Registration is handled by the higher education institution (IES) through INEP's Sistema Enade, not by the student individually.

How does ENADE differ from CREA registration?

ENADE is an academic assessment run by INEP/MEC to measure course quality. Professional registration with the Conselho Regional de Engenharia e Agronomia (CREA/CONFEA) is the separate legal licence, obtained after graduation, that allows you to practise engineering in Brazil.

Do these practice questions match the official exam format?

Not exactly. The official exam is written and answered in Portuguese and includes a discursive item plus a broad Formação Geral block on transversal themes such as human rights, climate change and social inclusion. This bank is an English-language multiple-choice study adaptation built from the official objetos de conhecimento; it is a study aid, not an official translation or a format simulation.
