where F 1 is the tension side force and F 2 is the slack side force. The quantity (F 1 F 2) is the net obtained from the horsepower flat belts, the value of C is between 2 and 3, depending upon conditions of installation. For Vbelts, use C = . The axial load produced from gearing must be obtained from considerations of the type of geartooth design used.

groove ball bearings are the most common type of bearing, and can handle both radial and thrust loads. Due to their lowfrictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the ball and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and
