Question

rlsu Problem 2. (25 pts) The hollow rod is made up of aluminum (G 3.9x10* psi). PART 1: Calculate (a) the torque T needed to cause an angle of twist of 5 and (b) the maximum shearing stress due to this torque and PAT 2: Suppose that the same Torque found in Part 1 (a) is applied to a solid rod (non-hollow) of the same length and cross sectional area, (c) calculate the new angle of twist, and (d) the corresponding maximum shearing stress. Hint: The angle of twist ф is in radians but your final answers should be in degrees rt rads 180) p= TL 4 It Given 3.9x10 75 in. aw 0.5 in.
