Question 1
Which of the following equations correctly relates the Modulus of Elasticity (E), Shear Modulus (G), and Poisson's ratio (μ) for an isotropic elastic material?
Correct Answer:
E = 2G(1 + μ)
Question 2
A steel bar of length L, cross-sectional area A, and coefficient of thermal expansion α is fixed at both ends. If the temperature of the bar is increased by ΔT, what is the magnitude of the thermal stress developed in the bar, assuming Young's modulus is E?
Correct Answer:
α·ΔT·E
Question 3
What is the maximum bending moment in a simply supported beam of span L carrying a uniformly distributed load of intensity w per unit length over its entire span?
Correct Answer:
wL²/8
Question 4
A solid circular shaft of diameter D has the same length and material as a hollow circular shaft. The hollow shaft has an outer diameter D and an inner diameter D/2. What is the ratio of the torque-carrying capacity of the solid shaft to that of the hollow shaft under pure torsion?
Correct Answer:
16/15
Question 5
Under a state of pure shear stress of magnitude τ on a two-dimensional element, what is the radius of the resulting Mohr's circle of stress?
Correct Answer:
τ
