The rod shown below is composed of two pieces: the diameter of piece AC is 3 in, and the diameter of piece CD is 2 in. Both pieces are made of brass: Young's modulus is E = 15x10 psi and the shear modulus is G = 5.6x10 psi. The applied external axial forces are Pc = 50 kips and Po = 30 kips. The applied extemal torques are Tg = 25 kip in and To= 10 kip in. (Hint: for...
