A carpenter uses a crowbar to remove the top of a box. The top has a resistance of 500 N. The carpenter applies an input force of 250 N. What is the mechanical advantage of the crowbar?

Use the formula mechanical advantage = output force/input force to solve the following problem.

Answer:

2

Explanation:

MA = Fout / Fin

MA = 500 N / 250 N

MA = 2

Answer:

Mechanical advantage, m = 2

Explanation:

It is given that,

The resistance of the top of the box, R = 500 N

Input force applied to the box, R' = 250 N

Let m is the mechanical advantage of the box. It is equal to the ratio of output force to the input force. Mathematically, it is given by :

[tex]m=\dfrac{R}{R'}[/tex]

[tex]m=\dfrac{500}{250}[/tex]

m = 2

So, the mechanical advantage of the crowbar is 2. Hence, this is the required solution.
