Question

By applying a force of 50N, a pulley system can lift a box with a mass of 20 kg. What is the mechanical advantage of the pulley system?

Answer 1

Mechanical Advantage of a pulley=4

Step-by-step explanation:

Mechanical Advantage of a pulley= Load/Effort

MA= 20*10(assuming 9.8 =10)/50

MA=200/50=4
