A mechanism shown in Fig. 2.68 has the following dimensions:
\(O A=200 \mathrm{~mm}, A B=1500 \mathrm{~mm}, B C=600 \mathrm{~mm}, C D=500 \mathrm{~mm}\) and \(B E=40 \mathrm{~mm}\). Locate all the instantaneous centres.
If the crank \(O A\) rotates uniformly at \(120 \mathrm{rpm}\) clockwise, determine

(a) the velocity of \(B, C\) and \(D\), and

(b) the angular velocity of links \(A B, B C\), and \(C D\).
