A 1.5-in-diameter bar has been machined from an AISI 1050 cold-drawn bar. This part is to withstand a fluctuating tensile load varying from 0 to 62 kip. Because of the ends, and the fillet radius, a fatigue stress-concentration factor Kf is 1.85 for 106 or larger life. Estimate the fatigue factor of safety based on achieving infinite life (use Modified Goodman criteria) and the yielding factor of safety. If infinite life is not predicted, estimate the number of cycles to...

A 1.5 kg , 20-cm-diameter turntable rotates at 50 rpm on frictionless bearings. Two 470 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick. Part A What is the turntable's angular velocity, in rpm, just after this event? Express your answer to two significant figures and include the appropriate units. w=?

(a) Calculate the settling velocity of glass spheres (density = 2467 kg/m3) having diameter as 1.5 mm in water. The slurry contains 65% by weight solid. Use Newton’s law. (b) Mixture of an ore (density 2000 kg/m3) and gangue (density 7000 kg/m3) is to be separated in a hydraulic elutriator. The mixture has following size distribution, which is valid for ore as well as gangue. Predict the upward velocity of water in elutriator so that entire ore is collected in...
