Draw an involute of a circle of 40 mm diameter. Also, draw a tangent and normal at any point on the curve.
A point P is 30mm behind the VP and 40 mm below the HP. Another point Q is 20mm in front of the VP and 30 mm above the HP. The distance between the projectors through P and Q is 80 mm. Draw the projections of the points. Find the length of the line joining them and its inclinations with the HP and the VP.
(OR)
A line AB 80 mm long is inclined at 30° to the HP and 45° to the VP. Its end A is 20 mm above the HP and 30 mm in front of the VP. Draw the projections of the line.

Draw the projections of a circle of 50 mm diameter resting in the HP on a point A on the circumference. Its plane is inclined at 45° to the HP and (a) the top view of the diameter AB making 30° with the VP; (b) the diameter AB making 30° with the VP.
(OR)
A pentagonal prism, side of base 25 mm and axis 50 mm long, rests with one of its edges on HP such that the base containing that edge makes an angle of 30° to the HP. Draw its projections when its axis is parallel to VP.
