Q4. In Fig. below the angular velocity of the crank OA is 600 r.p.s. Assume crank is rotating with

constant velocity.

Determine the linear velocity and acceleration of the slider D and the angular velocity and angular

acceleration of the link BD, when the crank is inclined at an angle of 75° to the vertical. The

dimensions of various links are: OA = 28 mm; AB = 44 mm; BC 49 mm; and BD = 46 mm. The

center distance between the centers of rotation O and C is 65 mm. The path of travel of the slider

is 11 mm below the fixed point C. The slider moves along a horizontal path and OC is vertical.
