In the swivelling joint mechanism shown in Fig. 3.17 (a), \(A B=300 \mathrm{~mm}, B C=800 \mathrm{~mm}, C D=400 \mathrm{~mm}\), \(A D=500 \mathrm{~mm}, B E=400 \mathrm{~mm}, E F=500 \mathrm{~mm}, E S=250 \mathrm{~mm}\), and \(F R=600 \mathrm{~mm}\). The crank \(A B\) rotates at \(20 \mathrm{rads} / \mathrm{s}\) and \(200 \mathrm{rad} / \mathrm{s}^{2}\). Determine

(a) the coriolis acceleration, and

(b) the sliding acceleration of link \(E F\) in the trunnion.
