Answer 5

[AI-generated answer — Explain Bot]

To find the mechanical advantage of the pulley, we need to divide the output force (force applied to the load) by the input force (force applied to the pulley). In this case, the output force is 21 N and the input force is also 21 N.

So, the mechanical advantage of the pulley is given by:

Mechanical Advantage = Output Force / Input Force

Mechanical Advantage = 21 N / 21 N

Mechanical Advantage = 1

Therefore, the mechanical advantage of the pulley is 1.

Answer: B. 1
