Answer all five questions

All questions carry equal marks

1. a) A fixed point is 75mm from a fixed straight line. A point 'P' moves such that its distance from the fixed point is twice its distance from the fixed straight line. Trace the path of the 'P' point and name the curve.
   b) A circle of 50 mm diameter rolls on a straight line without slipping. Trace the curve traced by a point 'P' on the circumference for one complete revolution of the circle. Name the curve.

2. a) A point P is 20 mm above HP and 30 mm in front of VP. Another point Q is 40 mm below HP and 20 mm behind VP. Draw projections of P and Q keeping the distance between their projectors equal to 80 mm. Draw a straight line joining their front views and determine its traces.
   b) Draw the projections of a line CD 80 mm long, inclined at 30° to HP and 45° to VP. The point C is 20 mm above HP and 30 mm in front of VP.


3. A pentagonal plane lamina of sides 30 mm is resting on HP on one of its corners with surface making an angle of 45° with HP. If the top view of the side resting on HP makes an angle of 30° with VP, draw the projections of the lamina.
