The uniform thin bars AB, BC, and CD have masses mAB = 2.3 kg, mBC = 3.2 kg, and mCD = 5.0 kg, respectively. The connections at A, B, C, and D are pinned joints. Letting R = 0.75 m, L = 1.2 m, and H = 1.55 m, and knowing that bar AB rotates at an angular velocity ωAB = 4 rad/s, compute the kinetic energy T of the system at the instant shown.
