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.
