Question

A pulley system has a single fixed pulley and a single movable pulley. Find out its mechanical advantage.

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B 2

We would have inconvenience to apply the effort in an upward direction and use a single fixed pulley to change the direction of effort.

Refer fig, at equilibrium $L=T+T=2T$ or $E=T$

Where $L$ is the total load

$\therefore M.A.=\frac{load}{effort}=\frac{2T}{T}=2$
