Draw the acceleration diagram for the Whitworth mechanism shown in Fig.3.15(a).

\[ \begin{aligned} O_{1} O_{2} & =300 \mathrm{~mm}, O_{1} A=200 \mathrm{~mm} \\ A B & =700 \mathrm{~mm}, B C=800 \mathrm{~mm} \\ \angle A O_{1} O_{2} & =45^{\circ} . \end{aligned} \]

The crank \(O_{1} A\) rotates at \(120 \mathrm{rpm}\) clockwise. Determine

(a) Velocity of ram \(C\),

(b) Coriolis acceleration,

(c) angular acceleration of \(A B\),

(d) angular acceleration of \(B C\), and

(e) acceleration of ram \(C\).
