ME 212 Lecture Notes - Lecture 4: Stress (Mechanics), Rivet, Compressive Stress
Document Summary
Bearing stress is the contact pressure between the separate bodies. It differs from compressive stress, as it is an internal stress caused by compressive forces. 1-12, assume that a 20-mm-diameter rivet joins the plates that are each 110 mm wide. The allowable stresses are 120 mpa for bearing in the plate material and 60. Determine (a) the minimum thickness of each plate; and (b) the largest average tensile stress in the plates. Calculate the maximum safe load p that can be applied if the shearing stress in the rivets is limited to 14 ksi and the bearing stress in the plates is limited to 18 ksi. Assume the applied load is uniformly distributed among the four rivets. 1-11b, find the minimum bolt diameter and the minimum thickness of each yoke that will support a load p = 14 kips without exceeding a shearing stress of 12 ksi and a bearing stress of 20 ksi.
