which of the machine components is designed under bending stress
​

Answer 1

Options for this question are:

a. Shaft

b. Arm of a lever

c. Key

The correct answer is "Arm of the lever."

What is a lever in the machine?

• The lever part of the machine is used to exert most of the force.
  
• It has such an important role that we can call it a 'machine in a machine.'
  
• It consists of two parts: handle and fulcrum.
  
• A lot of stress is used to make this component of the machine.

Thus, option b is correct.
