Crank \(O A\) in Fig.2.21

(a) is \(80 \mathrm{~mm}\) long and rotates clockwise about \(O\) at \(120 \mathrm{rpm}\). The connecting rod \(A B\) is \(450 \mathrm{~mm}\) long. Point \(C\) on \(A B\) is such that \(A C=150 \mathrm{~mm}\). A rod \(C E=400 \mathrm{~mm}\) is attached at point \(C\) which slides in a trunnion at \(D\). The end \(E\) is connected by a link \(E F=320 \mathrm{~mm}\) to the horizontally moving slider \(F\). Find

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

(b) the velocity of sliding of \(C E\) in the trunnion, and

(c) the angular velocity of \(C E\).
