ASSIGNMENT 3

UNIT III (Projection of Solids)

1. A hexagonal pyramid, side of base 25mm and axis 50mm long, rests with one of the edges of its base on HP and its axis is inclined at 30º to HP and parallel to VP. Draw it projections.(UQ)

2. A hexagonal prism, side of base 25mm and axis 50mm long rests with one of its base corners on HP such that its base makes an angle of 60º to HP and its axis is parallel to VP. Draw its projections.(UQ)

3. A pentagonal pyramid, side of base 25mm and axis 55mm long, lies with one of its slant edges on HP such that its axis is parallel to VP. Draw its projections.(UQ)

4. A tetrahedron of 40mm side rests with one of its edges on HP and perpendicular to VP. The triangular face containing that edge is inclined at 30º to HP. Draw its projections. (UQ)

5. A pentagonal pyramid side of base 20mm and axis 45mm long rests with one of its corners on HP such that the base in inclined at an angle of 60º to HP and one side of base is perpendicular to VP. Draw its projections. (UQ)

6. Draw the projections of a cone, base 30mm diameter and axis 50mm long, resting on HP on a point of its base circle with the axis making an angle of 45º with HP and parallel to VP. (UQ)

7. Draw the projections of a cylinder, base 30mm diameter and axis 40mm long, resting with a point of its base circle on HP such that the axis is making an angle of 30º with HP and parallel to VP. (UQ)

8. Draw the projections of a pentagonal prism of 30mm side of base and 65mm long lying on one of its longer edges on HP with one rectangular face perpendicular to HP such that the axis makes 60º with VP.(UQ)

9.  Draw the plan and elevation of a right regular pentagonal prism side of base 25mm and axis 58mm long when it is resting on its base on HP with one of its rectangular faces making an angle of 30º to VP.(UQ)
10. A pentagonal pyramid has an altitude of 60mm and base side 35mm. The pyramid rests with one of its sides of the base on HP such that the triangular face containing that side is perpendicular to both HP and VP. (UQ)

11.  A pentagonal pyramid of base side 30mm and axis length 60mm is resting on VP on one of its triangular faces with its axis is parallel to HP. Draw its projections.

12.  A cylinder of base diameter 50mm and axis length 70mm is resting on HP on one of its generators with its axis inclined at 50° to VP. Draw its projections.

13.  A tetrahedron of side 50mm is resting on VP on one of its edges with the face containing that edge is perpendicular to both HP and VP. Draw its projection.

14. A equilateral triangular prism 20mm side of base and 50mm long rests with one of its shorter edges on HP such that the rectangular face containing the edge on which the prism rests is inclined at 30° to HP. The shorter edge resting on HP is perpendicular to VP.

15. A square prism of base side 35mm and axis length 60mm is resting on HP on one of its longer edges with its axis inclined at 25˚ to VP. One of its faces containing the resting edge inclined at 25˚ to HP. Draw its projections.

16. A pentagonal pyramid of base edge 25mm and axis length 60mm rests on one base side on HP such that the highest base corner is 20mm above HP. Its axis is parallel to the VP. Draw its top and front views. (KVN)
