Question

What situation would give you a mechanical advantage? *

Answer 1

Answer:

D

Explanation:

In a fixed pulley system, there is load, carried bi the strings and also there is effort which is the number of the turns of strings or number of the wheels in the pulley system

Since

$mechanical \: advantage = \frac{load}{effort}$

There is M.A in the fixed pulley system

But in other objectives, there is load but they lack effort, hence they cannot give mechanical advantage
