Two distinct shafts are first joined in series and a single torque T is applied. Then, the same two shafts are joined in parallel under the same total torque T. If the lengths of both shafts are equal, find the product of the angle of twist in series (θs) and the angle of twist in parallel (θp). Let G and J denote the shear modulus and polar moment of inertia for each shaft.
