In the four-bar mechanism shown in Fig.3.8, the lengths of the various links are: \(A B=190 \mathrm{~mm}\), \(B C=C D=280 \mathrm{~mm}, A D=500 \mathrm{~mm}, \angle B A D=55^{\circ}\). The crank \(A B\) rotates at \(10 \mathrm{rad} / \mathrm{s}\) in the clockwise direction. Determine

(a) the acceleration of the links \(B C\) and \(C D\), and

(b) angular accelerations of \(B C\) and \(C D\).
