Question

Calculate the mechanical advantage if 48 N force is needed to overcome the load of
120 N. Justify whether it will work as a force multiplier or not?

Answer 1

Given:

Effort to overcome the force of the object ($F_{A}$)= $48$ N

Force of the object ($F_{B}$) = $120$ N

To find:

The mechanical advantage (MA)

Formula used:

$MA\;=\;\frac{F_{B} }{F_{A} }$

Where, $MA$ is the mechanical advantage,

$F_{B}$ is the force of the object

$F_{A}$ is the effort to overcome the force of the object.

Step-by-step Explanation:

$MA\;=\frac{120}{48}$

$MA\;= 2.5$

Here, $MA\;=\;2.5$ which is greater than $1$

Therefore, it will work as a force multiplier

Answer:

The mechanical advantage is $2.5$ and it will act as a force multiplier, since it is greater than $1$
