Problem 5-25/5-26/5-27/ Engineering Mechanics Materials

Engineering Mechanics problem with solution go to playlist to get more specific problems 5–25. The copper pipe has an outer diameter of 2.50 in. and an inner diameter of 2.30 in. If it is tightly secured to the wall at C and it is subjected to the uniformly distributed torque along its entire length, determine the absolute maximum shear stress in the pipe. Discuss the validity of this result. 5–26. A cylindrical spring consists of a rubber annulus bonded to a rigid ring and shaft. If the ring is held fixed and a torque T is applied to the shaft, determine the maximum shear stress in the rubber. 5–27. The assembly consists of the solid rod AB , tube BC,and the lever arm. If the rod and the tube are made of material having an allowable shear stress of tallow = 12 ksi, determine the maximum allowable torque T that can be applied to the end of the rod and from there the couple forces P that can be applied to the lever arm. The diameter of the rod is 2 in., and the outer and inner diameters of the tube are 4 in. and 2 in., respectively.
