The rod OA rotates counterclockwise with a constant angular velocity of θ˙ = 5 rad/s. Two pin-connected slider blocks, located at B, move freely on OA and the curved rod whose shape is a limacon described by the equation r=100(2−cosθ)mm. Determine the speed of the slider blocks at the instant θ = 135 ∘.
