Mechanical advantage can be calculated by which of the following expression?
A) input force/output force
B) output force/input force
C) input work/output work
D) output work/input work

Verified Answer :

This answer would be A) input force/output force

Mechanical advantage is defined as resistance force moved to the effort force used.

How do you calculate the mechanical advantage?

  • Mechanical advantage is defined as the force against a movement or an object to obtain the amplification of force.

  • The mechanical advantage is calculated as the ratio of output force to the input force.

The formula can be given as:

MA = \(\rm\dfrac{F_o}{F_i}\)

Where, F\(_o\) = Output force; F\(\rm_i\) = Input Force

Thus, the correct answer is Option B.
