2022 gate textile question 37

AB = original length; BD = total extension; CD = elastic extension;
BC = permanent set
With reference to the above schematic, consider the following statements:
P. For perfectly elastic material, BC = 0
Q. For perfectly elastic material, CD = 0
R. For perfectly plastic material, BC = 0
S. For perfectly plastic material, CD = 0
The combination of TRUE statements is

(A)P and Q
(B)Q and R
(C)R and S
(D)P and S
[Show Answer]

Option D is correct

Frequently Asked Questions | FAQs

What is elastic recovery ?

Elastic recovery refers to the ability of a material to return to its original shape after it has been stretched or deformed. This property is determined by the elasticity of the material, which is the extent to which it can be stretched or deformed while still returning to its original shape once the stretching force has been removed. Elastic recovery is a crucial property for many materials, especially in applications where the material needs to withstand repeated stretching and deformation without losing its shape or strength.
