Answer: A

Explanation: a measure of how much a machine multiplies the force applied to it

Mechanical advantage is defined as the ratio of force produced to force applied to the machine.

The correct option is:

Option A. a measure of how much a machine multiplies the force applied to it

Mechanical advantage is the ratio of force produced to the force applied. The mechanical advantage is calculated to assess the performance of the machine.

It can be calculated as:

[tex]\text{MA}&=\dfrac{{\text F}_\text {i}}{\text{F}_\text{o}}[/tex]

where,

  • Fi = input force
  • MA = Mechanical advantage
  • Fo = output force

Mechanical advantage is the measure of the force amplification achieved by a machine, tool, or mechanical device.

The mechanical advantage works on the law of the lever to obtain the desired output force.

Therefore, the correct option is A.
