Sample WBPSC AE Civil Practice Questions

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

1What is the relationship between Young's Modulus (E), Shear Modulus (G), and Poisson's ratio (μ)?
A.E = 2G(1 + μ)
B.E = 2G(1 - μ)
C.G = 2E(1 + μ)
D.G = 2E(1 - μ)
Explanation: Young's Modulus E and Shear Modulus G are related by the equation E = 2G(1 + μ), where μ is Poisson's ratio. This relationship is derived from the elastic response of materials under axial and shear stress conditions.
2If a material has a Young's Modulus of 200 GPa and a Bulk Modulus of 133.33 GPa, what is its Poisson's ratio?
A.0.25
B.0.33
C.0.20
D.0.30
Explanation: The relationship between Young's Modulus (E), Bulk Modulus (K), and Poisson's ratio (μ) is E = 3K(1 - 2μ). Substituting the values: 200 = 3 * 133.33(1 - 2μ) => 200 = 400(1 - 2μ) => 0.5 = 1 - 2μ => 2μ = 0.5 => μ = 0.25.
3A simply supported beam of span L carries a concentrated load W at its mid-span. What is the maximum deflection of the beam if its flexural rigidity is EI?
A.WL³ / (48EI)
B.WL³ / (3EI)
C.5WL³ / (384EI)
D.WL³ / (8EI)
Explanation: For a simply supported beam with a central point load W, the maximum deflection occurs at the mid-span and is equal to WL³ / (48EI). This is calculated by integration methods or moment-area theorems.
4A cantilever beam of length L carries a point load W at the free end. What is the deflection at the free end?
A.WL³ / (3EI)
B.WL³ / (8EI)
C.WL³ / (48EI)
D.WL³ / (2EI)
Explanation: The deflection at the free end of a cantilever beam under a point load W is WL³ / (3EI) and the slope is WL² / (2EI). This is determined by the double integration or conjugate beam method.
5For a fixed beam of span L carrying a central concentrated load W, what is the value of the bending moment at the supports?
A.WL / 8
B.WL / 4
C.WL / 12
D.WL / 16
Explanation: A fixed beam with a central point load W has fixed-end moments of WL / 8 at both supports. The bending moment at the mid-span is also WL / 8 (in magnitude), making the total moment change WL/4.
6A circular solid shaft of diameter D is subjected to a torque T. What is the maximum shear stress induced in the shaft?
A.16T / (πD³)
B.32T / (πD³)
C.64T / (πD³)
D.8T / (πD³)
Explanation: According to the torsion equation T/J = τ/r, where J = πD⁴/32 is the polar moment of inertia and r = D/2. Solving for shear stress τ yields τ = (T * D/2) / (πD⁴/32) = 16T / (πD³).
7What is the effective length of a column of actual length L if it is fixed at one end and free at the other?
A.2.0 L
B.0.5 L
C.0.7 L
D.1.0 L
Explanation: For a column fixed at one end and free at the other, the buckled shape is equivalent to half of a pinned-pinned column of length 2L. Therefore, its theoretical effective length is 2.0 L.
8What is the ratio of Euler's buckling load for a column fixed at both ends to that of a column pinned at both ends, assuming identical material and cross-section?
A.4
B.2
C.16
D.8
Explanation: Euler's buckling load is P = π²EI / L_eff². For a pinned-pinned column, L_eff = L, so P_pinned = π²EI / L². For a fixed-fixed column, L_eff = 0.5L, so P_fixed = π²EI / (0.5L)² = 4π²EI / L². The ratio P_fixed / P_pinned is 4.
9According to the theory of pure bending, what is the bending stress at the neutral axis of a beam subjected to bending?
A.Zero
B.Maximum tensile stress
C.Maximum compressive stress
D.Average stress of the cross-section
Explanation: The bending stress formula is σ = My/I. At the neutral axis, the distance y from the neutral axis is zero, which means the bending stress σ is also zero. The neutral axis undergoes no elongation or contraction during bending.
10What is the ratio of the maximum shear stress to the average shear stress in a circular cross-section beam?
A.4/3
B.3/2
C.8/3
D.2
Explanation: For a circular cross-section, the maximum shear stress occurs at the neutral axis and is equal to 4/3 times the average shear stress (τ_max = 4/3 * V/A).
