Question

If mechanical advantage of a machine is 4, what does it indicate?

Answer 1

it is the ratio of output force to input force.... it indicates that there will be multiplication i.e ,if you apply 100N force to your machine then it will be 400N

Answer 2

Explanation:

Answer: Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
