Resolve Example 7.3 by using the MATLAB fatigue strength code available at Wiley website and named as (Fatigue_Strength_and_Factors_Affecting.m). Use only the plain carbon steel material and the von Mises failure theory.
A shaft is transmitting a maximum of 25 [kW] or 33.5 [hp] and running at 3000 [rpm] in the clockwise direction. It is subject to a maximum bending moment that is equal to the maximum applied torque. Find the internal stresses if the shaft has a cylindrical diameter of 45 [mm] or 1.75 [in]. The selected material is set as HR AISI 1040 or ISO C40. Find the safety factor for each applicable theory of failure.
If this shaft function is as a camshaft made of gray cast iron, find the safety factor for each applicable theory of failure. This camshaft can be made of the gray cast iron designation ASTM A 48 class 40 or ISO 185 300.
