THEORY OF STRUCTURES III

Rotational effect of force is called

• Momentum

• Movement

• Rotor

• Moment

When a material is loaded within elastic limit, the material will regain its shape and size when the load is removed.

• Agree

• Disagree

The bending stress in a beam is __________ bending moment

• equal to

• less than

• more than

• directly proportional to

When a bar is subjected to a change of temperature and its deformation is prevented, the stress induced in the bar is

• tensile stress

• compressive stress

• shear stress

• thermal stress

The ratio of stress and strain is known as

• Modulus of elasticity

• Young's modulus

• Both a. and b.

• None of the above

A rigid body has Poisson's ratio equal to

• 0

• 1

• less than 1

• greater than one

Two parallel, equal and opposite forces acting tangentially to the surface of the body is called as

• Complementary stress

• Compressive stress

• Shear stress

• Tensile stress

Which stress is induced in a member, when expansion or contraction due to temperature variation is prevented?

• Compressive stress

• Tensile stress

• Thermal stress

• None of the above

The beam having one end free and one end fixed is called as

• Cantilever beam

• Continuous beam

• Overhang beam

• Simply supported beam

You push your finger into a ball of play-doh and it keeps its new shape. This is an example of

• elasticity

• plasticity

• hardness

• tensile strength
