Bulk properties of solids 2

Question 1

shearing stress

Answer 1

When the force is applied tangentially to the surface, shape changes without change in volume.

Question 2

hydraulic stress

Answer 2

When a solid body undergoes change in volume without change in geometric shape.

Question 3

tensile stress (longitudanal stress)

Answer 3

If a stress applied results in the increase of the length of an object then we call it tensile strength.

Question 4

compressive stress

Answer 4

the stress applied results in decrease in length.

Question 5

strain

Answer 5

change in configuration/original configuration

Question 6

types of strain

Answer 6

1. Longitudinal strain
2. Bulk
3. Shear

Question 7

longitudinal strain

Answer 7

Due to repeated action of tensile stress, longitudinal strain develops in a body

Question 8

Hooke’s law

Answer 8

Extension produced in a wire is directly proportional to the load applied within the elastic limit.

Question 9

Modulus of Elasticity (K)

Answer 9

It is a stress required to develop unit strain

Question 10

Difference between elasticity and elastic limit.

Answer 10

Elastic limit is the property of a body while elasticity is the property of a material.

Question 11

Elastic after effect

Answer 11

It is a temporary delay, in regaining the original configuration by an elastic body after removal of deforming force.

Question 12

Define yielding point

Answer 12

Yielding point is a region when the load is removed from the body comes back to the original shape after the time lag it is a property of elastic after effect.
