2. A cylinder with a nominal 2.5 inch ID, a 4.0 inch OD, and a 3.0 inch length is to be mated with a solid shaft with a nominal 2.5 inch diameter. The cylinder and shaft are made from steel, with Sy = 100 kpsi and E 30 Mpsi. The coefficient of friction for the steel interface is 0.7. = The maximum and minimum allowable diameters for both the cylinder hole and the shaft are given as Dmax=2.5012 inch, Dmin=2.5 inch; dmax=2.5028 inch, dmin=2.5021 inch (a) (b) Determine the maximum amount of torque that can be transmitted through this joint, assuming the shaft and cylinder are manufactured within their tolerances. Determine yielding condition for the cylinder, due to the stress from the interference fit. Use the Von Mises yielding theory.
