QUESTION 2: LOCI (CAMS)

Given:

* The incomplete displacement diagram.

© The vertical centre line of the cam shaft as reference
on the drawing sheet.

The specifications for the movement are as follows:

* The cam shaft rotates clockwise

Over the first 60°, the follower rises 36 mm at an
uniform velocity

There is a dwell period for the next 30°.

Over the next 90°, the follower rises a further 34 mm
at simple harmonic velocity.

Over the final 180°, the follower returns to its original
position at uniform acceleration & retardation.
Minimum distance from cam profile to cam shaft
centre is 10 mm.

.

Instruction
2.1. Draw a displacement graph with a rotational scale of
30° equal to 10 mm and a follower displacement

scale of 1:1 for the given motion. Label the graph.

2.2. Project, to scale 1:1, and draw the cam profile that
the displacement diagram would generate using the
vertical centre line as reference. The arrow indicating
the direction of rotation must be shown

Show ALL necessary construction. [36]
