There is a dwell period for the next 30°. It rises to its maximum displacement of 80 mm over the next 90° with uniform motion. «lt descends 40 mm over the next 90° with simple harmonic motion. It returns to its original position with uniform acceleration and retardation over the remainder of the rotation. Instructions: Using centre point P on the drawing sheet, draw, to scale 1: 1, the camshaft and wedge-shaped follower in the given position. ¢ Draw to a rotational scale of 30° = 8 mm anda displacement scale of 1 : 1, the complete displacement graph for the required motion. * Using the given position of the follower as 0°, project and draw the cam profile from the displacement graph. ‘Indicate the direction of rotation on the cam profile with an arrow. ¢ Indicate the rotational scale of the graph.
