## Theory of Structures The ratio of shear stress and shear strain of an elastic material, is

Shear Modulus
Both A. and B.
Modulus of Rigidity
Modulus of Elasticity

## Theory of Structures Pick up the correct statement from the following:

The moment of inertia is calculated about the axis about which bending takes place
If tensile stress is equal to axial stress, the section experiences compressive stress
If tensile stress is less than axial stress, the section experiences compressive stress
All of these

## Theory of Structures For calculating the allowable stress of long columns σ0 = σy/n [1 - a (1/r)²]is the empirical formula, known as

Parabolic formula
Perry
Rankine
Straight line formula

## Theory of Structures A shaft subjected to a bending moment M and a torque T, experiences

Maximum shear stress = 16 T/πd³
Maximum bending stress = 32M/πd³
Neither A nor B
Both A and B

H = 0
All of these
M = 0
V = 0

## Theory of Structures A lift of weight W is lifted by a rope with an acceleration f. If the area of cross-section of the rope is A, the stress in the rope is

[W (2 + g/f)]/A
[W (2 + f/G)]/A
(1 – g/f)/A
[W (1 + f/ G)]/ A
