df 1n mon diame ss: F size 0.70 V): A cold drawn C-1025 steel rod of circular cross section is subjected to a variable bending moment of 10,000 in-lb to 17,000 in-lb, as the axial load varies from-2,000 lb to 5,000 lb. The maximum bending moment occurs at the same instant that the axial load is maximum. Determine the required diameter of the rod for a factor of safety N-2.3? The steel rod is connected to the support which causes...

A 1045 hot rolled steel rod undergoes axial cyclic loading from a minimum stress of 2 kpsi to a maximum of 10 kpsi. The rod has a hole in the center of bar, with a Kt 1.7, and notch sensitivity factor 0.9. The yield strength of bar is 45 kpsi, ultimate strength 82 kpsi, fully endurance limit of 20 kpsi, fatigue strength fraction 0.85. 1. a. Using modified goodman criteria, find FOS b. lfinfinite life is not predicted estimate the...

II) A 1 square threaded screw is 35" long between the nut and collar. The axial load is 3500b and the torque in the screw between the nut and collar is 2500 in-lb. Using C 2 and neglecting the threads and stress concentration, determine the safety factor N if a steel with a yield point in tension of 55,000 psi is used. The root diameter is 0.783". (25 points)
