7-52 (30pts) Calculate the accelerations of points A, B, and C when w = 20 rad/sec. Assume =0. Use Ls=2.6 L6=1.8 Ls=2.6 0604-3.8 L2=1.35 in 44=1.36 ng L61.80 72 8 = 14 86 = 88 L4=1.36 004 = 1.22@ 56.5 060 = 3.86 @ 33 Step 1: You need to do vector loop on mechanism comprising Link 2, Link 3, Link 4 and 0-04 to find motion of link 4 as a function of L2 motion input. Step 2: Once L4 motion (angle and their derivatives) is fully found, motion analysis of four bar portion comprising L4, L5, L6 and 06-04 can be done with L4 motion as input. 8. =88 from the problem statement, so e, can be found easily. L4 is distance between B and 04
