Question

A machine has a mechanical advantage of 5. What force should be applied to the machine to make it apply 3000 N to an object? 0. 002 N 600 N 3000 N 15,000 N.

Answer 1

The magnitude of force needed to be applied on the machine is of 15,000 N.

How mechanical advantage is related to output force?

The ratio of force output to the applied force gives the value of the mechanical advantage. In other words, the mechanical advantage has a direct relation with the force output.

Given data:

The value of the mechanical advantage is, MA = 5.

The magnitude of applied force is, F = 3000 N.

Since the output force is the force exerted on the machine. Then the relation is given as,

MA = F'/F

here,

F' is the magnitude of the force exerted on the machine.

Solving as,

5 = F'/3000

F' = 5 × 3000

F' = 15,000 N

Thus, we can conclude that the magnitude of force needed to be applied on the machine is of 15,000 N.
