Do the first part of Problem 7.7 this time including the effects of two rigid cylinders, respectively of uniform mass per unit length ρ1 and ρ2 and polar moments of inertia of the cross section I1 and I2, placed at the ends z = 0 and z = L of the bar.

Problem 7.7:

Derive the differential equation and boundary conditions for the torsional oscillation of a bar in the absence of warping in terms of the rotation angle θ(z,t) and using the polar moment of inertia of the cross-vectors .

Also discuss under what conditions the effect of the geometric cross section of the bar will not be a factor in the solution.
