The formula for pulley is T1/T2 = R1/R2, where T1 and T2 are the tensions in the ropes on each side of the pulley, and R1 and R2 are the radii of the pulley on each side.
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
The circumference of a pulley is the distance around the outside edge of the pulley. It is calculated by using the formula C = Οd, where C is the circumference and d is the diameter of the pulley. The circumference is important when determining the speed and distance traveled by a belt or rope running around the pulley.
To calculate the force required to lift something with a pulley system, use the formula: Force = Weight / (number of supporting ropes). The weight is the force of gravity acting on the object being lifted. The number of supporting ropes is the number of ropes in the pulley system that are supporting the weight.

For a pulley, it is driver RPM x driver diameter = driven RPM x driven diameter. Keep in mind that the diameter you should use is the diameter where the belt is riding in the pulley. For instance, an A belt in an AB pulley will ride lower in the pulley than it would in an A pulley. For sprockets, the formula is the same, but replace the diameter with # teeth. It looks like this. driver rpm x # teeth of driver sprocket = driven RPM x # teeth of driven sprocket
IMA of a pulley= the number of ropes supporting the load. An easier way is to count how many times the rope wraps around the wheel. :)

There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
a coumpound pulley is when there is a fixe pulley and movable pulley working together

To calculate the mechanical advantage of a movable pulley system, you divide the load force by the effort force. The formula is MA = Load Force / Effort Force. The mechanical advantage of a movable pulley is always 2 because the effort force is half the load force when using a system with a movable pulley.
