The reciprocating rectilinear motion mechanism consists of a disk pinned at its center at A that rotates with a constant angular velocity ωAB, a slotted arm CD that is pinned at C, and a bar that can oscillate within the guides at E and F. As the disk rotates, the peg at B moves within the slotted arm, causing it to rock back and forth. As the arm rocks, it provides a slow advance and a quick return to the reciprocating bar due to the change in distance between C and B.

For the position shown, determine

(a) The angular velocity of the slotted arm CD and the velocity of the bar

(b) The angular acceleration of the slotted arm CD and the acceleration of the bar

Evaluate your results for ωAB = 90 rpm, R/h = 0.5, and d = 0.12 m.
