The assembly consists of three disks A, B, and C that are used to support the load of 140 kN. Determine the smallest diameter d1 of the top disk, the largest diameter d2 of the opening, and the largest diameter d3 of the hole in the bottom disk. The allowable bearing stress for the material is (sb)allow = 350 MPa and allowable shear stress is tallow = 125 MPa.
Problem 1-85 The assembly consists of three disks A, B, and C that are used to support the load of 140 kN. Determine the smallest diameter d of the top disk, the largest 1 diameter d of2he opening, and the largest diameter d of the hole in 3e bottom disk. The allowable bearing stress for the material is ( allow b 350 MPa and allowable shear stress is allow 125 MPa. Step-by-step solution Step 1 of 4Calculate the diameter of the opening by considering the allowable shear stress in thedisk: Here, is the allowable shear stress in the disk, P is the load, and A is the circumferential area, t is the thickness of the plate. 6 3 Substitute, 125 x 10 Pa for = 0.01 m for t, and 140 x 10 N for P. d2 0.0356 m d2 35.6mm Therefore, the diameter of the opening is .\n
