Sample PEC EPE Mechanical Practice Questions

Try these sample questions to review concepts for the PEC EPE Mechanical exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Evaluate the definite integral ∫₀³ (3x²) dx.

A.27

B.9

C.18

D.81

Explanation: ∫₀³ 3x² dx = [x³]₀³ = 27 − 0 = 27. Power-rule integrals appear in beam deflection and energy calculations.

2For matrix [[3, 1], [2, 2]], what is the larger eigenvalue?

A.4

B.1

C.3

D.2

Explanation: det([[3−λ,1],[2,2−λ]]) = (3−λ)(2−λ)−2 = λ²−5λ+4 = 0 → λ = 4 or 1. Larger root is 4.

3A sample of five tensile strengths (MPa) is 200, 210, 220, 230, 240. What is the sample standard deviation (n−1)?

A.15.81 MPa

B.14.14 MPa

C.20.00 MPa

D.10.00 MPa

Explanation: Mean = 220. Deviations: −20,−10,0,10,20. Sum of squares = 1000. s² = 1000/4 = 250 → s ≈ 15.81 MPa.

4Solve dy/dx + 2y = 0 with y(0) = 5. What is y(1)?

A.5e⁻²

B.5e²

C.5/2

D.10e⁻²

Explanation: Separating: dy/y = −2 dx → ln|y| = −2x + C. With y(0)=5, y = 5e⁻²ˣ. At x=1, y=5e⁻².

5Using the trapezoidal rule with one interval, approximate ∫₀² x² dx.

A.2

B.4

C.8/3

D.1

Explanation: Trapezoidal: (b−a)/2 · [f(a)+f(b)] = 2/2 · (0+4) = 2. Exact value is 8/3 ≈ 2.67, so this is a coarse approximation.

6A pressure gauge reads 102 kPa when the true pressure is 100 kPa. Absolute error is 2 kPa. Relative error is:

A.2%

B.0.2%

C.2 kPa

D.102%

Explanation: Relative error = |absolute error|/true value = 2/100 = 0.02 = 2%.

7Which instrument is most appropriate for measuring very high steady fluid temperatures in a furnace (~1200 °C)?

A.Type K or R thermocouple / optical pyrometer

B.Mercury-in-glass thermometer

C.Bimetallic strip thermostat only

D.Bourdon tube

Explanation: Thermocouples and radiation pyrometers cover high furnace temperatures; liquid-in-glass and Bourdon devices are unsuitable.

8A flowmeter has accuracy ±1% of full scale (FS = 100 L/min). At a reading of 20 L/min, the maximum percentage error relative to reading is approximately:

A.5%

B.1%

C.0.2%

D.20%

Explanation: Absolute error band = 0.01×100 = 1 L/min. Relative to 20 L/min reading: 1/20 = 5%. FS accuracy hurts low-range readings.

9In first-angle orthographic projection, the top view is placed:

A.Below the front view

B.Above the front view

C.To the right of the front view only

D.On an isometric plane

Explanation: In first-angle projection (common in many ISO contexts), the plan (top) appears below the elevation (front).

10A unilateral tolerance of +0.05 / −0.00 mm on a 50 mm shaft means the acceptable size range is:

A.50.00 to 50.05 mm

B.49.95 to 50.05 mm

C.49.95 to 50.00 mm

D.50.05 only

Explanation: Unilateral +0.05/−0.00 allows only growth above nominal: 50.00–50.05 mm.

About the PEC EPE Mechanical Exam

The Engineering Practice Examination (EPE) Part-II for Mechanical Engineering and Allied Disciplines is PEC’s discipline paper for Registered Engineers seeking Professional Engineer (PE) registration. It covers Mechanical, Industrial & Manufacturing, and Aeronautical (Aerospace) candidates. It is a 3-hour open-book MCQ paper with 60 questions: 25 Breadth items aligned to the undergraduate mechanical curriculum (math, measurement, design, manufacturing, thermo-fluids) and 35 Depth items in one opted specialization (Thermo-Fluids Engineering, Manufacturing Engineering, Design Engineering, Control Engineering, or Aeronautical Engineering—Aerospace). Candidates must also pass Part-I (common, 40 MCQs, 2 hours) at 60% independently.

Exam sponsor: Pakistan Engineering Council (PEC) / EPDC. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

PEC EPE Mechanical: Suggested Study Strategy

1Map Breadth hours to syllabus weights (Design/Manufacturing/Thermo-Fluids each 30% of Breadth)

2Choose a Depth track that matches your daily practice (e.g., Thermo-Fluids for plant/HVAC work)

3Build a tabbed open-book kit early—steam tables, property charts, and design standards

4Practice timed 60-question sets in three hours to match Part-II pacing

5Drill calculation MCQs in thermo, fluids, strength, and manufacturing metrology

6Keep Part-I (management, ethics, environment, hazards, communication) warm if attempting both parts the same day

7Confirm cycle dates, centres, and fee voucher rules on cpd.pec.org.pk before applying

8Only bring a simple calculator—programmable devices and phones are prohibited

Frequently Asked Questions

How many questions are on PEC EPE Mechanical Part-II?

Part-II Mechanical & Allied has 60 multiple-choice questions: 25 Breadth (Section A) plus 35 Depth in your opted specialization (Section B). The paper lasts three hours and is open-book for bound books and standards only.

What is the passing score for EPE Part-II?

You must score at least 60% in Part-II. Part-I and Part-II are passed independently; failing one part does not cancel a pass in the other within the allowed retake window.

What Depth specializations can Mechanical candidates opt?

Per the official Mechanical & Allied syllabus, Depth options include Thermo-Fluids Engineering, Manufacturing Engineering, Design Engineering, Control Engineering, and Aeronautical Engineering (Aerospace only). Attempt only the Depth area you select.

Who is eligible to sit for the EPE?

A PEC Registered Engineer with at least five years of relevant practical experience since registration (to the announcement closing date) and at least 17 CPD credit points since 10 July 2010 or initial registration, whichever is later.

Is Part-II open book?

Yes. Part-II allows books and bound copies of standards/texts as described for the discipline. Loose notes, handouts, and electronic devices (except a simple calculator) are not permitted.

How is the EPE fee paid?

Fees are published on each cycle’s notice. Payment must be made through a Bank Alfalah system-generated voucher from the CPD portal; deposits by other methods are not accepted. Always confirm the current amount before paying.
