The mechanism shown in Fig. 2.67 has the following dimensions:
\(O_{1} A=50 \mathrm{~mm}, A B=200 \mathrm{~mm}, C D=60 \mathrm{~mm}, O_{2} B=100, O_{1} O_{2}=150 \mathrm{~mm}, A C=C B\), and \(C E=\) \(E F=100 \mathrm{~mm}\). The crank \(O_{1} A\) rotates at \(210 \mathrm{rpm}\). Determine by instantaneous centre method

(a) velocity of slider \(F\),

(b) angular velocity of \(C E\), and

(c) velocity of sliding of \(C E\) in the swivel block \(D\).
