Question 1
A steel bar of 20 mm diameter and 1 m length is subjected to an axial tensile load of 50 kN. If the Young's modulus of steel is E = 200 GPa, what is the elongation of the bar?
Correct Answer:
0.796 mm
Question 2
For an isotropic material, what is the relation between the Young's Modulus (E), Shear Modulus (G), and Poisson's ratio (mu)?
Correct Answer:
E = 2G(1 + mu)
Question 3
A cantilever beam of length L carries a uniformly distributed load of intensity w per unit length over its entire length. What is the maximum deflection of the beam at the free end? (EI is the flexural rigidity)
Correct Answer:
wL^4 / (8EI)
Question 4
At a point in a strained material, the principal stresses are 100 MPa (tensile) and 40 MPa (compressive). What is the maximum shear stress at this point?
Correct Answer:
70 MPa
Question 5
What is the ratio of torque transmission capacity of a solid shaft of diameter D to a hollow shaft of outer diameter D and inner diameter d = D/2, if both are made of the same material and subjected to the same maximum shear stress?
Correct Answer:
16/15
