• 39. in the system shown in figure p2.25, the inertia, j, of radius,r, is constrained to move only about the stationary axis a. a viscous damping force of translational value f v exists between the bodies j and m. if an external force, f(t), is applied to the mass, find the transfer function, gðsþ ¼ uðsþ=fðsþ.
