PROBLEM 1 PLEASE help and explain in details
Problem 1. Below figure shows a notched bar under reversed push-pull axial load P. The bar is cut from AISI 1030 cold-drawn steel. Using a design factor n,-2 and reliability of 95%, estimate the largest force Put that can be applied on the bar without causing failure of the bar. Consider both fatigue failure and yielding due to maximum load in the first cycle by DE theory. 2.5 mm 35 mm 30...

Problem 1 The machined steel bar shown in the figure undergoes fully reversed axial loading at a nominal alternating stress of 30 ksi. 1. Find the safety factor for an infinite life of the bar if the critical section of this filleted bar in tension is assumed at the shoulder fillet. 2. How many cycles of stress can be expected? Given: The corrected endurance limit Se = 35 ksi. Material Ultimate Tensile Strength Sut = 100 ksi. Material Yield Strength...
Figure Q3 shows (1) an straight shaft and (2) a stepped shaft
Figure Q3 shows (1) an straight shaft and (2) a stepped shaft. Both are made of steel having Su = 150 ksi and Sy = 90 ksi. Surfaces of the shafts are fine-ground. Varied torque T of 0 to 20x103(Ibxin) is applied. a) Estimate the S-N curve with 95% reliability under torsion loading. b) For the straight shaft, calculate the safety factor against infinite fatigue life with 95% reliability. c). For the stepped shaft, calculate the safety factor against infinite fatigue life with...
