The kinematic diagram of one of the cylinders of a rotary engine is shown in Fig.3.34(a). The crank \(O A\) which is vertical and fixed, is \(50 \mathrm{~mm}\) long. The length of connecting \(\operatorname{rod} A B\) is \(125 \mathrm{~mm}\). The line of stroke \(O B\) is inclined at \(50^{\circ}\) to the vertical. The cylinder is rotating at a uniform speed of \(300 \mathrm{rpm}\), in a clockwise direction, about the fixed centre \(O\). Calculate

(a) acceleration of the piston inside the cylinder, and

(b) angular acceleration of connecting rod.
