Consider the compound shaft KDQC which is composed of a 300 mm long solid rod DQC (G = 35 GPa) fitted snuggly (up to a length of 200 mm) into a 600 mm (G = 63 GPa) long pipe KDQ. The rod has a diameter of 170 mm and the pipe has an outer diameter of 210 mm with a wall thickness of 20 mm. Two concentrated torques are applied at Q and C with magnitudes and directions as shown. Note that the end K of the pipe is fixed to a wall. ø210mm 20mm K C 2.5T T 400mm 200 100 mm mm If the maximum allowable twist at any section of the entire compound shaft is 0.0005 rad, determine the following: 1.
