Sample TTD AE Practice Questions

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

1According to Hooke's Law, within the elastic limit of a material, stress is directly proportional to which of the following?
A.Strain
B.Area
C.Modulus of elasticity
D.Poisson's ratio
Explanation: Hooke's Law states that within the elastic limit, the stress developed in a material is directly proportional to the strain produced. Mathematically, stress = E × strain, where E is the Modulus of Elasticity. The other options are constants or geometric features, not the proportional variable.
2What is the typical range of Poisson's ratio for structural steel?
A.0.25 to 0.33
B.0.10 to 0.15
C.0.45 to 0.50
D.0.05 to 0.08
Explanation: Poisson's ratio (the ratio of lateral strain to longitudinal strain) for structural steel under elastic conditions typically ranges between 0.25 and 0.33, with 0.30 being the standard design value. Concrete generally has a lower range (0.10 to 0.20), while highly elastic rubber approaches the theoretical limit of 0.50.
3What is the SI unit of kinematic viscosity?
A.m²/s
B.N-s/m²
C.kg/m-s
D.m/s²
Explanation: Kinematic viscosity is defined as dynamic viscosity divided by fluid density. Its SI unit is m²/s, while N-s/m² (or Pascal-seconds) and kg/m-s represent dynamic viscosity. The unit m/s² is for linear acceleration.
4The slump test for concrete is used to determine which property?
A.Workability
B.Compressive strength
C.Tensile strength
D.Durability
Explanation: The slump test measures the consistency and workability of fresh concrete before it sets. A higher slump value indicates a more fluid, workable mix, whereas compressive and tensile strengths are hardened concrete properties determined by crushing and splitting tests.
5Contour lines that cross each other indicate which of the following topographic features?
A.An overhanging cliff
B.A vertical cliff
C.A uniform slope
D.A saddle or pass
Explanation: Contour lines represent elevations and generally do not intersect or cross. The only exception is an overhanging cliff, where lines cross, or a vertical cliff, where multiple contour lines merge into a single line. Vertical cliffs do not cross but merge.
6In soil mechanics, void ratio is defined as the ratio of the volume of voids to which of the following?
A.Volume of solids
B.Total volume of soil
C.Volume of water
D.Volume of air
Explanation: Void ratio (e) is defined as the ratio of the volume of voids (Vv) to the volume of soil solids (Vs). Porosity (n), on the other hand, is the ratio of the volume of voids to the total soil volume (V). The volume of water to voids is the degree of saturation.
7What is defined as the distance along the road that a driver can see ahead at any given time?
A.Sight distance
B.Passing zone
C.Right of way
D.Camber
Explanation: Sight distance is the length of road visible ahead to the driver, allowing them to control the vehicle safely. Camber is the transverse slope provided to drain rainwater, right of way is the land width acquired for the road, and passing zones are designated overtaking lengths.
8What is the minimum initial setting time of Ordinary Portland Cement (OPC) recommended by Indian Standards?
A.30 minutes
B.60 minutes
C.600 minutes
D.10 hours
Explanation: According to IS codes, the initial setting time of Ordinary Portland Cement (OPC) must not be less than 30 minutes, allowing sufficient time for mixing, transport, and placing. The final setting time must not exceed 600 minutes (10 hours) to ensure the structure gains strength in a reasonable period.
9Which of the following instruments is used to measure rainfall depth in meteorology and hydrology?
A.Rain gauge
B.Anemometer
C.Lysimeter
D.Tensiometer
Explanation: A rain gauge measures the depth of liquid precipitation over a set period. An anemometer measures wind speed, a lysimeter measures evapotranspiration, and a tensiometer measures soil moisture tension.
10What is the pH value of completely neutral water at 25 degrees Celsius?
A.7
B.0
C.14
D.6.5
Explanation: Neutral water has a pH value of 7 at 25 °C. Values below 7 indicate acidic solutions, while values above 7 are basic or alkaline. Raw water supply standard limits are usually between 6.5 and 8.5.

About the TTD AE Exam

The TTD Assistant Engineer Examination is conducted by Tirumala Tirupati Devasthanams (TTD) for recruiting technical engineers (Assistant Engineers and Assistant Technical Officers) for their civil and electrical divisions. The selection process is primarily based on a Computer-Based Test (CBT) followed by document verification. Only candidates of Hindu religion are eligible. This practice bank focuses on the technical objective written test stage.

TTD AE: Suggested Study Strategy

1Focus heavily on the core diploma-level technical syllabus since the questions are conceptual and application-oriented.
2Practice numerical problems on structural mechanics, concrete mix design, and hydraulic flows.
3Familiarize yourself with Indian Standard codes (IS 456, IS 800) as many questions directly reference concrete and steel design specifications.
4Revise environmental engineering parameters like water quality standards and sewer design criteria.
5Manage your time during practice exams to handle calculation-heavy questions efficiently within the time limit.
