For the mechanism shown, find all instant centers of velocity & the velocities of points B and C. w 2 = 10 rad/s. Also find the mechanical advantage Dr. Al-Abduljabbar ME 363: H FiFi FoFo

1. Get Primary Centers (2,3) (1,4) at ∞ (1,2) (3,4) (1,3) 2. Get Secondary Centers B) Center (24): 12, 14 & 23, 34 (2,4) A) Center (13):12, 23 & 14, 34 Dr. Al-Abduljabbar ME 363: H

3. Velocities 1. v A = v C.23 = w 2 * r 2 = 10 (rad/s)* 2 (2cm) = 20 cm/s 2. v A = v C.23 = w 3 * r AC v B = w 3 * r BC v C = w 3 * r CC.13 Dr. Al-Abduljabbar ME 363: H From graph, measure lengths to get: w 3 = 3.8 rad/s (from 2) v B = 3.8 * 2.6 = 10 cm/s (from 3) v B = 3.8 * 5.2 = 20 cm/s (from 4) vBvB vAvA
