Q1:

The stress at which extension of the material takes place more rapidly as compared to the increase in load is termed as the __________ point of the material.

A elastic

B ultimate

C yielding

D breaking

ANS:C - yielding

The stress at which extension of the material takes place more rapidly as compared to the increase in load is termed as the yielding point of the material. At this point, the material undergoes plastic deformation, meaning it experiences permanent changes in shape without an increase in load. This is a crucial point in material behavior as it marks the transition from elastic to plastic deformation.
