Problem 7. The 30-mm diameter shaft is subjected to the vertical and horizontal loadings of two pulleys as shown. It is supported on two journal bearings at A and B which offer no resistance to axial loading. Furthermore, the coupling to the motor at C can be assumed not to offer any support to the shaft. The shaft is subjected to both M₂ and My internal bending moment components. (a) Draw a bending moment diagram for each component. (b) Since all axes through the circle's center for circular shaft are principal axis, then the resultant M = √ √M²+ M² can be used to determine the maximum bending stress. Determine the location and y 150 N 1 m Z 150 N 1 m E 60 mm 1 m 100 mm B 1 m 400 N 400 N
