1.Following are the basic types of stress except

• Tensile stress
• Compressive stress
• Shear stress
• Volumetric stress

2.The bending moment diagram for a simply supported beam carrying a uniformly distributed load of w per unit length, will be

• a horizontal line
• a vertical line
• an inclined line
• a parabolic curve

3.A shaft is said to be in pure torsion if

• Turning moment is applied at one end and other end is free
• Turning force is applied at one end and other end is free
• Two opposite turning moments are applied to the shaft
• Combination of torsional load and bending load is applied to the shaft

4.If diameter of a shaft is doubled the power transmitted capacity will be

• Either twice or half
• Four times
• Eight times
• SAME

5.The volumetric modulus of elasticity is called

• Bulk modulus
• Shear modulus
• Proof modulus
• Young’s modulus
