The weights of the uniform thin pin-connected bars AB, BC, and CD are WAB = 4 lb, WBC = 6.5 lb, and WCD = 10 lb, respectively. Letting ϕ = 47°, R = 2 ft, L = 3.5 ft, and H = 4.5 ft, 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.
