In the mechanism shown in Fig.3.33, the crank \(O A\) rotates at \(20 \mathrm{rpm}\) anti-clockwise and gives motion to the sliding blocks \(B\) and \(D\). The dimensions of the various links are: \(O A=300 \mathrm{~mm}, A B=1200 \mathrm{~mm}\),

\(B C=450 \mathrm{~mm}\), and \(C D=450 \mathrm{~mm}\). Determine

(a) velocities of sliding at \(B\) and \(D\),

(b) angular velocity of \(C D\),

(c) linear acceleration of \(D\), and

(d) angular acceleration of \(C D\).
