The eneine mechanism shown in Fig. 8.38 has crank OB 50 mm and length of connecting rod AB 225 mm. The centre of gravity óf the rod is at G which is 75 mm from B. The engine speed is 200 r.p.m. 45° Fig. 8.38 For the position shown, in which OB is turned 45° from OA, Find 1. the velocity of G and the angular velocity of AR and 2. the acceleration of G and angular acceleration of A B The eneine mechanism shown in Fig. 8.38 has crank OB 50 mm and length of connecting rod AB 225 mm.
