Question

Calculate the mechanical advantage of a
pulley in which a person puts in an effort of
50 N to lift a load 150 N. ???
Please Answer !​

Answer 1

$\red{\mid{\underline{\overline{\textbf{Answer}}}\mid}}$

Mechanical advantage of a pulley system is defined as the ratio of Load to be overcomed to the effort applied. Defined by Expression :-

$ma = \frac{l}{e}$

Now we have been given that :-

• Load at pulley = 150N
• Effort applied by pulley = 50
• Mechanical advantage = ?

Now after inputting the known values in the expression we get :-

$ma = \frac{l}{e}$

$ma = \frac{150}{50}$

$ma = \huge \cancel \frac{150}{50}$

$ma = 3n$

Therefore the Mechanical advantage of pulley is 3Newton.
