∙ 13y agoi really dk
they can be used to decrease the force needed to lift the loads , as if u have to lift a weight of 50 N and u used a robe hanged on a single pulley , u will have to exert a force of 50 N, while if the rope was hanged on 2 successive pulleys , u will act by a force of 25 N and consequently if u have 3 pulleys u will act by a force of (50/3)N and so on.....

∙ 12y agoPulley is a disc like mechanical component which has groove on its periphery.The shape of groove depends upon the shape of belt which have to be used.
these pulley and belt assembly are used in power transmission when the distance of transmission is quite greater and where gear transmission (gear train due to longer distance) can not be used.
generally "V" shaped (trapezoidal cross section) belt is prefer to avoid slip between pulley and belt.

How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
