Question : 44 of 78

Marks: +1, -0

The pulley system drawn lifts a load of

150 {\N}

when an effort of

60 {\N}

is applied. Find its mechanical advantages.

Solution:

\;\text " Here load "\;(L)\;=150 {\N}

\;\text " effort "\;(E)\;=60 {\N}

∴ \;\text " Mechanical advantage "\;\;=\;{\;\text " load "\;( {\L})}/{\;\text " effort "\;( {\E})}

\;=\;{150 {\N}}/{60 {\N}}=2.5
