What is the velocity ratio of single movable pulley how does the friction inthe pulley bearing affect it? Share with your friends Share 1 Deepak Kumar answered this Dear Student, In a single movable pulley is a pulley that is free to move up and down,and is attached to a ceiling or other object by two lengths of the same rope.Examples of movable pulleys include construction cranes, modern elevators,and so me types of weight lifting machine sat the gym.Load Lis attached to the movable pulley.Arope is fixed point in ceiling that passes through the movable pulley.In order to lift the load"L"by"X"meters,the effort"E"needs to travel the distance of 2X meters.(The entire rope needs to be pulled by"E"for a distance of 2X.Now,Velocity Ratio equals (Distance travelled by"E")divided by(Distance travelled by"L")So it becomes:2 X/X. This equals to 2 Since it is a ratio.it has no units of measurement.Regards -12 View Full Answer
