Specifications: The minimum distance from the centre of the cam shaft to the cam profile = 20 mm * Camshaft = @ 20 mm * Rotation = clockwise Motion: The disc cam rotates at constant velocity imparting the following uniform motion to the roller-ended follower: © Over the first 60° the follower is at rest. * Over the next 60° the follower rises to a height of 57 mm. * There is a dwell period for the next 45° * Over the next 45° the follower falls 20 mm. © There is a dwell period for the next 60° * Over the final 90° the follower returns to its original position. Instructions: * Using a horizontal scale of 30° equal to 8 mm and a displacement scale of 1 : 1, draw the displacement graph for the given motion. * Label the displacement graph and include the scale Draw, to scale 1 : 1, the given roller-ended follower in the correct position Project and draw the cam profile from the displacement graph. Show the direction of rotation on the cam profile. * Show ALL necessary construction [36] oa 60.
