The dimensions of the various links of the mechanism shown in Fig.2.28

(a) are \(\mathrm{OA}=30 \mathrm{~mm}\), \(A B=75 \mathrm{~mm}, B D=100 \mathrm{~mm}\). The crank \(O A\) rotates at \(120 \mathrm{rpm}\). Determine the velocity of the slider \(D\) and angular speed of links \(A B, B C\), and \(B D\).
