The shaft shown in Figure P4.46 is 200 mm long between self-aligning bearings A and B. Belt forces are applied to a sheave in the center, as shown. The left end of the shaft is connected to a clutch by means of a flexible coupling. Nothing is attached to the right end.
(a) Determine and make a sketch showing the stresses acting on the top and side elements, T and S, located adjacent to the sheave. (Neglect stress concentration.)
(b) Represent the states of stress at T and S with three-dimensional Mohr circles.
(c) At location S, show the orientation and stresses acting on a principal element, and on a maximum shear element.
