The crank and slotted lever mechanism shown in Fig.2.30

(a) has the dimensions of its various links as follows:
\(O A=200 \mathrm{~mm}, A B=100 \mathrm{~mm}, O C=400 \mathrm{~mm}\), and \(C D=300 \mathrm{~mm}\). The crank \(A B\) rotates at \(75 \mathrm{rpm}\). Determine

(a) velocity of ram, and

(b) angular speed of slotted lever \(O C\).
