ABC can be modeled as a single rigid body. Its mass is 300 kg and the moment of inertia about its center of mass is I = 360 kg-m2. Starting from rest with its CG 2 meters above the ground, the hydraulic cylinder pushes the arm ABC to the current position. At this position, the angular velocity of the arm is 1.4 rad/sec (CCW) and its angular acceleration is 0.6 rad/s2. How much work did the hydraulic cylinder exert on the arm?T1+ Vg1+ Ve1+ U1-2= T2+ Vg2+ Ve2What equation, and what terms are zero?Okay for IA, it is a fixed axis of rotationIs it okay to use IA?This reduces toSolve for U.T2= ½ mvG2+ ½ IGϖ2= ½ 300 vG2+ ½ 360 ϖ2vG= vA + ϖx r = r ϖ
