Question

Question 3 The mechanism is used on a machine for the manufacturing of a wire product. Because of the rotational motion of link AB and the, sliding of block F, the segmental gear lever DE undergoes general plane motion. If AB is rotating at WAB = 5 rad/s, determine the velocity of point E at the instant shown. 50 mm 20 mm F 20 mm 50 mm 200 mm B 45 WAB = 5 rad/

only on Drawing BC link 2450 velocity Vg 3 Ve Here, VB = A B X WAB = 0.0585 0.25 m/s as vel of all point & en same link should be same it o th long Ne cosa 5 = VB - Ve 0.25 = 0.35355 m/s Now Cosas WBC = Ve sin45 0.25 = 1.25 rad/s Bc 0.2. velocity of point 't is resultant of two velocities DEX Wee = 0.05 X 1.25 0.0625 m/s 135° Vc E so VE = ((0.35355)² + (.0625)2 + 2x0.35355x0.0625605135 VE = 0.3125 m/s » VE =
