In the mechanism shown in Fig. 2.53, the crank AB, 70 mm long, rotates clockwise at 110 rev/min. CD is 140 mm long. Link BD is 260 mm long and slides through a swivelling pin E at the lower end of rod EF. EF slides in vertical guides as shown. For the position shown, find the angular velocity of DB and the linear velocity of F. IF 24 (Ans. 1-395 rad/s; 0-452 m/s; -130 mm. D E 140 mm k -260 mm- FIG. 2.53 A
