Two pin-connected slider blocks, located at B , move freely on OA and the curved rod whose shape is a limaçon described by the equation r = b(c − cos(θ)). Determine the speed of the slider blocks at the instant θ = θ1. Given: θ' = 5 rad s b = 100 mm c=2 θ 1 = 120 deg Solution: θ = θ1 r = b( c − cos ( θ ) ) r' = b sin ( θ ) θ' 112 ...
