Question

to lift a load to roof, you apply 21 n of force to a pulley. the pulley applies 21 n of force to the load. what is the mechanical advantage of the pulley?

Answer 1

Answer:

The mechanical advantage of the pulley is 1.

Explanation:

The mechanical advantage of the pulley is given as

$MA=\frac{F}{f}$

Here, MA is represent for the mechanical advantage of the pulley, F is load for lift and f applied force.

Given F =21 N and f= 21 N.

Substitute the given values, we get

$MA=\frac{21N}{21N}$

MA = 1.

Thus, the mechanical advantage of the pulley is 1.
