If K1 = 0 in the torsional system of Problem, the system becomes a degenerate two-DOF system with only one natural frequency.
Discuss the normal modes of this system as well as a linear spring-mass system equivalent to it.
Show that the system can be treated as one of a single DOF by using the coordinate ? = (θ1 - θ2),
Problem
Determine the normal modes of the torsion al system shown in Fig. P5-5 for K1 = K2 and J1 = 2j2 .
Suppose you have two boxes that conceal what is inside, althougheach has two wires coming out of the interior. You have atyour disposal some batteries, wire and identical flash tlight bulbs.
