Question

What will be the mechanical advantage of a lever which helps to lift a load of 60 kgf when an effort of 20 kgf is applied?

Answer 1

1.Given data,

Load = 60 kgf

Effort = 20 kgf

We know that,

2. Mechanical advantage = $\frac{Load}{Effort}$

Mechanical advantage =$\frac{60kgf}{20kgf}$

Mechanical advantage =3 kgf

Hence, the mechanical advantage of the machine is 3 kgf
