The Steel Part Shown Is Subjected To A Force F The Shaft Is Circular And Has A Polished Surface Also The Diameter Of 1
The Steel Part Shown Is Subjected To A Force F The Shaft Is Circular And Has A Polished Surface Also The Diameter Of 1 (140.47 KiB) Viewed 21 times
The steel part shown is subjected to a force F. The shaft is circular and has a polished surface. Also, the diameter of the part, D=0.75in. The ultimate tensile strength Su​=60ksi, i. Find the magnitude of the load F that will cause a fatigue life of 1,000 cycles if it is fully reversed. ii. Using the Gerber criterion, find the factor of safety if F that varies from 0 to 500lb. Will the part fail under this applied fluctuating load or not? Why? If failure is predicted, estimate the number of cycles to failure.
