Question

If a 50N force is applied to a lever and the lever is then able to lift a 150N object, what is the mechanical advantage (MA) of the lever?

A) MA = 0.33
B) MA = 1.5
C) MA = 3
D) MA = 300

Answer 1

The mechanical advantage of the lever is 3, which means the lever multiplies the input force by three times to lift the load.

Step-by-step explanation:

To find the mechanical advantage (MA) of the lever, we divide the output force by the input force. Since the lever lifts a 150N object with a force of 50N, the mechanical advantage is calculated as:

MA = Output force / Input force = 150N / 50N = 3

Therefore, the correct answer is C) MA = 3. This number represents how many times the input force is multiplied by the lever to lift the load.
