Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Item 1 used to intermittently operate a piece of equipment at the end of a lifter arm. The lifter is in contact with the highest point of the cam at the instant shown and the lifter is constrained to move only in the vertical direction. The cam has a radius of r = 4.5 in and is rotating about point O, which is offset from the center by a distance c = 3.0 in. The cam's angular position is measured from the positive x axis and is positive clockwise. The angular velocity and acceleration are positive clockwise.
