Question

The figure below shows a sewing needle bar mechanism O₁ABO₂CD wherein the different dimensions are as follows: Crank O₁A = 16 mm; ; vertical distance between O₁ and O₂ = 40 mm; ∠β=45⁰ horizontal distance between O₁ and O₂ = 13 mm; O₂B = 23 mm; AB = 35 mm; ∠O2BC=90⁰ ; BC = 16 mm; CD = 40 mm. D lies vertically below O₁. Find the velocity of needle at D for the given configuration. The crank O₁A rotates at 400 rpm.
