Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2021 and IES 2021 examinations :

1.The intensity of stress which causes unit strain is called

unit stress
bulk modulus
modulus of rigidity
modulus of elasticity
principal stress.

2.The Young's modulus of a wire is defined as the stress which will increase the length of wire compared to its original length

same amount
four times.

3.Percentage reduction of area in performing tensile test on cast iron may be of the order of


4.If the radius of wire stretched by a load is doubled, then its Young's modulus will be

become four times
become one-fourth
remain unaffected.
