A machine is designed to lift an object with a weight of 12 newtons. If the input force for the machine is set
at 8 newtons, what is the mechanical advantage of the machine?

m = 1.5

Explanation:

We have,

The input force for the machine is set is 8 N and the machine is designed to lift an object with a weight of 12 newtons.

We need to find the mechanical advantage of the machine. It is defined as the ratio of output force to the input force. Its formula is given by :

So the mechanical advantage of the machine is 1.5

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
