Question 1
A steel bar of 20 mm diameter and 2 m length is subjected to an axial tensile load of 50 kN. If the Young's modulus of steel is 200 GPa, what is the elongation of the bar?
Correct Answer:
1.59 mm
Question 2
A body of mass 10 kg is placed on a rough horizontal surface with a coefficient of static friction of 0.4. If a horizontal force of 30 N is applied to the body, what is the magnitude of the frictional force acting on it? (Take g = 10 m/s²)
Correct Answer:
30 N
Question 3
A cantilever beam of length L carries a concentrated load W at its free end. If the flexural rigidity of the beam is EI, what is the maximum deflection of the beam?
Correct Answer:
WL³ / 3EI
Question 4
A solid circular shaft of diameter D is subjected to a torque T. What is the maximum shear stress induced in the shaft?
Correct Answer:
16T / (pi * D³)
Question 5
At a point in a strained material, the principal stresses are sigma_x = 80 MPa (tensile) and sigma_y = 20 MPa (compressive). What is the maximum shear stress at this point?
Correct Answer:
50 MPa
