Crack AB of a slider crack mechanism shown in Figure 2 rotate at a constant speed of 300 rpm in clockwise direction. The connecting rod BC has a length of 1 m and incline at 45o to vertically positioned piston C. No angle or length for AB is given in the original question, thus I assume the angle is 70o because of the rough drawing I did here. Draw the displacement diagram of the mechanism shown in Figure 2 to scale. Use a vector diagram to determine the velocity of the piston C and connecting rod BC. Calculate the acceleration of piston C and the angular acceleration of connecting rod BC.

Draw the profile of a cam with oscillating roller follower for the following motion : (a) Follower to move outwards through an angular displacement of 20° during 120° of cam rota- tion. (b) Follower to dwell for 50° of cam rotation. (c) Follower to return to its initial position in 90° of cam rotation with uniform acceleration and retardation. (d) Follower to dwell for the remaining period of cam rotation. The distance between the pivot centre and the roller centre is 130 mm and the distance between the pivot centre and cam axis is 150 mm. The minimum radius of the cam is 80 mm and the diameter of the roller is 50 mm.
