Question

Determine the mechanical advantage of a simple machine which helps to lift a load of $75kgf$ when an effort of $15kgf$ is applied.

Answer 1

Step 1 : Given data

Load =$75kgf$

Effort = $15kgf$

Step 2 : Calculating the mechanical advantage

Formula for the mechanical advantage is given as, $M.A=\frac{Load}{Effort}$

So, $M.A=\frac{75kgf}{15kgf}$

M.A = $15$.

Hence, the mechanical advantage is $15$.
