mechanical design A shank with mill scale of 400 mm length is supported freely at its two ends. It is acted upon by central concentric cyclic load having a minimum value of 10 kN and a maximum value of 60 kN. Knowing that the factor of safety is 1.5 and the size factor is 0.85. The material properties depends upon your choice from the attached Table A-21. After a while a second loading was added to the shank of cyclic torque that varies from 300 N.m CW to 100 N.m CCW. Fine the percentage change in the shank diameter between the two loading cases. pls solve fast

Write legibly, provide given, step by step manual solution , and diagram for below problem.  Determine the maximum diameter of a taper pin for use to fix a lever to a shaft, if it is to transmit a maximum torque of 750 in-lbs. The shaft diameter is 3 inches and the material allowable stress is 17000 psi. Use factor of safety of 2.  (Ans. d = 0.1935 in)

Torque in = 40nm  Holding torque out  = 896nm    8.Using your answers from the gear box above, and given that the input shaft has a diameter of 12 mm and the output shaft has a diameter of 15 mm, both shafts are made from aluminium. When this transmission system was operated, it failed. Identify the position where the failure occurred and the reason for this failure. Suggests improvements to the system to overcome the failure mode. The shear strength of aluminium is 207 MPa.

Problem 17 A joint shown has the basic layout shown in the diagram below. (All dimensions on the diagram are in inches.) A single pin of diameter 0.5 inches (A = 0.2 in2) holds together the yoke and bar as shown. The material has an ultimate strength in tension of 80 ksi, and an ultimate strength in shear of 45 ksi. The load P has a value of 10000 lb. By examining the shear stress in the pin, the normal stress in the yoke, and the normal stress in the bar, find the overall factor of safety for the joint. P=10,000 lb YOKE -0.5 PIN BAR P=10,000 lb 1.5- 20 1.5 0.5 0.5
