What is the difference between true stress/strain and engineering stess/strain? And how do I calculate them?
A rotating shaft of 20 mm diameter is simply supported.
The shaft is loaded with a transverse load of 10 kN as shown in
the figure. The shaft is made from AISI 1095 hot-rolled steel. The
surface has been machined. The shaft operate at
temperature T = 450 °C. Consider a reliability factor of 95%.
Determine
(a) Calculate the reaction forces R, and R₂ (2 points)
(b) Draw the shear force and bending moment diagrams
and determine the maximum bending moment and
shear force. (6 points)

(c) Determine the critical location of the shaft and the maximum effective stresses. (3 points)
(d) Calculate the safety factor against yielding. Does the shaft undergo local yielding? (2 points)
(e) Determined the endurance limit, adjusted as necessary with Marin factors. (12 points)
(f) Calculate the fatigue factor of safety based on achieving infinite life. (2 points)
