Solve Prob. 665 if the moment M = 50 N m is applied about the y axis

Solve Prob. 6€“65 if the moment M = 50 N ˆ™ m is applied about the y axis instead of the x axis. Here I_y= 1/4 Ï€ (0.04 m)(0.08 m)³.

Data from 6-65

A shaft is made of a polymer having an elliptical cross section. If it resists an internal moment of M = 50 N ˆ™ m, determine the maximum bending stress in the material

(a) Using the flexure formula, where I_z = ¼ Ï€(0.08 m)(0.04 m)³,

(b) Using integration. Sketch a three-dimensional view of the stress distribution acting over the cross-sectional area. Here I_x = ¼ Ï€(0.08 m)(0.04 m)³.
