(1 Point) You decide to remake the shaft in problem 3 with Cold-Drawn AISI 1010 Steel. Calculate the endurance limit for the shaft. You can assume the temperature factor is equal to one. The shaft needs to be 90% reliable, and it has a key slot machined into it to hold the gear. Report your answer in kpsi rounded to one decimal place. The shaft characteristics are as follows: Length – 20 in; Diameter – 1in;
