Let us see this with some examples. Two angles in math are said to be corresponding when they are being referred in a way of equality. Angles made by two Parallel Lines when they are cut by a transversal or the angles when formed in an Isosceles Triangle are the Corresponding Angles. In both cases corresponding angles are equal in measure.
Flywheel - Pulley. Background. The classical flywheel (Wiki) is used typically with various engines (Wiki) to smooth out the power to drive a load. They also can be used as energy storage devices. A pulley (Wiki) is a disk that can turn on a shaft and has a groove to engage a drive belt or something like a rope. A gear (Wiki) is similar to a pulley but has teeth that engage other teeth on another gear. This web page started out with my interest in DC permenant magnet samll motors.
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. A movable pulley is a pulley that moves with the load. The movable pulley allows the effort to be less than the weight of the load. The movable pulley also acts as a second class lever. The load is between the fulcrum and the effort. The main advantage of a movable pulley is that you use less effort to pull the load. The main disadvantage of a movable pulley is that you have to pull or push the pulley up or down. If you add a second pulley, the amount of effort to lift the heavy object is much less . For example, to lift a box weighing 150 N, one would need to exert 150 N of force without the help of pulleys. However, by using just two pulleys, the person would only need to use 50 N of force. A combined pulley makes life easier as the effort needed to lift the load is less than half the weight of the load. The main advantage of this pulley is that the amount of effort is less than half of the load.
