A load of 75 kgf is raised with a Pulley system with an effort of 25 kgf what is the mechanical advantage, velocity ratio,efficiency of the system 
Asked by Samrat | 30 Jun, 2018, 08:51: PM
answered-by-expert Expert Answer
Mechanical advantage = load / effort = 75 / 25 = 3
 
ideally velocity ratio should be equal to mechanical advantage and efficiency should be 100 %
