1. A semicircular plate of 80 mm diameter has its straight edge in the V.P. and inclined at 45° to the H.P. The surface of the plate makes an angle of 30° with the V.P. Draw the projections.

2. Draw the projections of a circle of 80 mm diameter having the end A of the diameter AB in the H.P. the end B in the V.P. and the surface is inclined at 30° to the H.P. & 60° to the V.P.

3. ABCDE is a regular pentagonal plate of 40 mm side and has its corner A on H.P. The plate is inclined to H.P. such that the top view lengths of edges AB and AE are each 35 mm. The side CD is parallel to the both the reference planes. Draw the projections of the plate and find its inclination with H.P.

4. A circular plane of 60mm diameter, rests on V.P on a point A on its circumference. Its plane is inclined at 45° to V.P. Draw the projections of the plane when
(a) The front view of the diameter AB makes 30° with H.P. and
(b) The diameter AB it self makes 30° with H.P. (EEE, May.2008 Reg. Set:2)

5. A plate having shape of an isosceles triangle has a base of 50mm long and altitude 70 mm. It is so placed that in the front view it is seen as an equilateral triangle of 50 mm sides one side is inclined at 45° to XY. Draw its top view. . (IT,May. 2008 Reg. Set:4)

PROJECTIONS OF SOLIDS:

1. A tetrahedron of 5 cm long edges is resting on the ground on one of its faces, with an edge of that face parallel to the V.P. Draw its projections and measure the distance of its apex from the ground.

2. Draw the projections of a square pyramid having one of its triangular faces in the V.P. and the axis parallel to and 40 mm above the H.P. base 30 mm side, axis 75 mm long.

3. Draw the projections of a cone, base 50 mm diameter and axis 75 mm long lying on a generator on the ground with the top view of the axis making an angle of 45° with the V.P.
