Question

A force of 50 N is applied to the end of a lever to lift a rock that is 350 N. What is the mechanical advantage of the lever?

Answer 1

Answer:

MA = 7, Actual

explaination:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantages
