w 2-18 The disk in Fig. P2-18 has an = 120 r/min and a = 132 rad/s². Let OR = 38.1 mm and OC = 25.4 mm. Deterinine V, V. A, A, A, and A. Make a full-size drawing of the disk and show the B 135° Figure P2-18 vectors at points B and C using the following scales; velocity, 1 mni 1 mm = 0.240 m/s2. Determine graphically Ves, As, Ac, and ACIB = 0.0120 m/s; acceleration.
