When the shaft carries no axial load, then F = 0 and when the shaft carries axial tensile load, then α = 1. Example A hollow shaft is subjected to a maximum torque of kNm and a maximum bending moment of 3 kNm. It is subjected, at the same time, to an axial load of 10 kN.

A ball bearing is a circular joint that connects a rotating part to another, usually stationary, part of a machine. It allows the rotating part to provide or receive structural support while significantly reducing the amount of friction caused by the rotation. Figure 1 shows an example of a selfaligning ball bearing.

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

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
