Vg = VB + V gB
Resolving parallel to link BC R
Vg cos(83) = - VB cos(90 + 02 + 03)
-7.6 cos(90 +31.7 – 88.7)
cos(50.8)
= -10.08 m/s
Resolving perpendicular to link BC K
VgB = Vg sin(6g) -VB cos(02 + 63) = -10.08 sin(50.8) – 7.6 cos(31.7 – 88.7) = -11.95 m/s
VgB
WCB * 0.5 BC = -5.48 + 0.5 * 1.33 = -3.64
SOMETHIING IS WONRG: CHECK SIGN OF Vg
