QUESTION: 1

The maximum strain energy stored in a body without permanent deformation is

Solution:
QUESTION: 2

The maximum strain energy stored in a material at its elastic limit per unit volume is known as

Solution:
QUESTION: 3

Modulus of resilience of a material is the area of the stress-strain curve up to

Solution: Modulus of resilience is the area under the stress strain curve up to the elastic limit.

QUESTION: 4

Modulus of resilience is defined as

Solution: Modulus of resilience is the proof resilience per unit volume.

QUESTION: 5

For a body of volume V and stresses due to gradually applied load, the strain energy stored is

Solution: For gradually applied load

U =

QUESTION: 6

The maximum strain energy stored in a circular shaft, under pure torque, (T) is expressed as Umax is

Solution:

U =

U=

QUESTION: 7

Strain energy stored in a solid circular shaft subjected to torsion is proportional to

Solution: Strain energy due to torsion

U =

∴ U ∝ 1/GJ

QUESTION: 8

The strain energy stored in a body due to suddenly applied load compared to when it is applied gradually is

Solution: Strain energy due to sudden load is twice as much as gradual load.

In sudden applied load, h → 0

If = 1 + = 2

QUESTION: 9

The maximum stress produced in a bar when a load is applied suddenly is 40N/mm2. If the same load is applied gradually, the stress produced is

Solution: σsudden = 2σgradual

40 = 2(σgradual)

σgradual = 20N/mm2

QUESTION: 10

A load P is applied onto a body gradually and the elongation observed is 12 mm. If the same load P is applied suddenly. The instantaneous elongation in the body will be

Solution: δgradual = 12mm

δsudden = 2(δgradual ) = 24 mm
