Fig. 3- 5 shows the internal structure of an internal combustion engine which has AB = 10cm, and BC = 10 3 cm. The angle velocity of the crank shaft is 30rad/s, and LACB is shown in position. 1) Draw the kinematic diagram of this mechanism. 2) Find out all instantaneous centers. 3) Determine the velocity of the piston in the position shown. 30 B Fig. 3-5
