How to Calculate Mechanical Advantage (MA) of a Simple Machine

What is the formula to calculate Mechanical Advantage (MA) of a simple machine?

A) Length x Width

B) Input Force / Output Force

C) Work / Force

D) Power / Time

Answer:

B) Input Force / Output Force

Mechanical Advantage (MA) is a measure of the amplification of force achieved by using a simple machine. The formula to calculate Mechanical Advantage is Input Force divided by Output Force. It represents how much the force applied to a machine is multiplied. By knowing the input force and output force, you can easily calculate the Mechanical Advantage of a simple machine.

For example, if you apply an input force of 100 N to a simple machine and the machine produces an output force of 200 N, the Mechanical Advantage would be calculated as follows:

MA = Input Force / Output Force

MA = 100 N / 200 N

MA = 0.5

So, in this scenario, the Mechanical Advantage of the simple machine would be 0.5.
