Question

If the distance between the levers input force and the fulcrum is 8 cm, and the distance between the fulcrum and the output force is 24 cm, what is the ideal mechanical advantage of the lever?

Answer 1

Answer:

Ideal mechanical advantage of the lever is 3.

Explanation:

Given that,

The distance between the levers input force and the fulcrum is 8 cm, $d_i=8\ cm$

The distance between the fulcrum and the output force is 24 cm, $d_o=24\ cm$

To find,

The ideal mechanical advantage of the lever.

Solution,

The ratio of the distance between the fulcrum and the output force to the distance between the levers input force and the fulcrum is called the ideal mechanical advantage of the lever. It is given by :

$m=\dfrac{d_o}{d_i}$

$m=\dfrac{24}{8}$

m = 3

So, the ideal mechanical advantage of the lever is 3.
