Question

an effort force of 200n is applied to an ideal machine to move a 750n resistance a distance of 30cm. what is the mechanical advantage of the machine?

Answer 1

Gives

Effort force (F)=200N

Friction force

$F_{ap}=750N$

$MA=\frac{friction force}{effort force }$

$MA=\frac{750}{200}=3.75$
