1. An equilateral triangular lamina of
25mm side lies with one of its edges on HP such that the surface of the lamina
is inclined to HP at 60°. The edge on which it rests is inclined to VP at 60°.
Draw the projections.
2. An isosceles triangular plate of
negligible thickness has base 25mm long & altitude 35mm. It is so placed on
HP such that in the front view it is seen as an equilateral triangle of 25mm
sides with the side that is parallel to VP is inclined at 45° to HP. Draw its
top and front views. Also determine the inclination of the plate with the
reference plane.
3. A triangular lamina of 25mm sides
rests on one of its corners on VP such that the median passing through the
corner on which it rests is inclined at 30° to HP and 45° to VP. Draw its
projections.
4. A square lamina ABCD of 40mm side
rests on corner C such that the diagonal AC appears to be at 45° to VP. The two
sides BC and CD containing the corner C make equal inclinations with HP. The
surface of the lamina makes 30° with HP. Draw its top and front views.
5. A square plate of 30mm sides rests on
HP such that one of the diagonals is inclined at 30° to HP and 45° to VP. Draw
its projections.
6. The top view of a square lamina of
side 30mm is a rectangle of sides 30mm x 20mm with the longer side of the
rectangle being parallel to both HP and VP. Draw the top and front views of the
square lamina. What is the inclination of the surface of the lamina with HP and
VP?
7. A pentagonal lamina of sides 25mm is
resting on one of its edges on HP with the corner opposite to that edge
touching VP. This edge is parallel to VP and the corner which touches VP is at
a height of 15mm above HP. Draw the projections of the lamina. Also determine
the inclinations of the lamina with HP and VP and the distance at which the
parallel edge lies from VP.
8. A pentagonal lamina having edges 25mm
is placed on one of its corners on HP such that the perpendicular bisector of
the edge passing through the corner on which the lamina rests is inclined at 300
to HP and 450 to VP. Draw the top and front views of the lamina.
9. Draw the top and front views of a
hexagonal lamina of 30mm sides having two of its edges parallel to both VP and
HP and one of its edges is 10mm from each of the planes of projection. The
surface of the lamina is inclined at an angle of 600 to the HP.
10. A Hexagonal lamina of 30mm sides
rests on HP with one of its corners touching VP and the surface inclined at 450
to it. One of its edges is inclined to HP at 300. Draw the front and
top views of the lamina in its final position.
11. Draw the projections of a circular
plate of negligible thickness of 50mm diameter resting on HP on a point A on
the circumference, with its plane inclined at 450 to HP and the top
view of the diameter passing through the resting point makes 600
with VP.
12. A circular lamina of 30mm diameter
rests on VP such that one of its diameters is inclined at 300 to VP
and 450 to HP. Draw its top and front views in this position.
