# Engineering Drawing Questions and Answers – Projection of Solids

«

This set of Engineering Drawing Multiple Choice Questions & Answers (MCQs) focuses on “Projection of Solids”.

1. When the axis of a solid is parallel to a plane, the projection of the solid shows the true shape and size of its base.
a) False
b) True

Explanation: A solid with the axis perpendicular to the projection plane will have the true shape and size of its base.

2. When the axis of a solid perpendicular to H.P., __________ should be drawn first.
a) top view
b) front view
c) side view
d) rare view

Explanation: When the axis is perpendicular to the H.P., then the top view projection is the true shape and size of the base. Hence drawing top view will be the easiest and so it should be drawn first.

3. When the axis of a solid perpendicular to V.P., __________ should be drawn first.
a) top view
b) front view
c) side view
d) rare view

Explanation: When the axis is perpendicular to the V.P., then the front view projection is the true shape and size of the base. Hence drawing front view will be the easiest and so it should be drawn first.

4. When the axis of a solid parallel to H.P and V.P., __________ should be drawn first.
a) top view
b) front view
c) side view
d) rare view

Explanation: When the axis is parallel to H.P and V.P., then neither the front view nor the top view projection has the true shape and size of the base. Hence drawing the projection on an auxiliary plane which is perpendicular to both H.P and V.P, that is the side view will be the easiest and so it should be drawn first.

5. While drawing a projection, If the first top view is drawn and then the front view is projected from the top view. Then the axis of the solid is _____________
a) parallel to V.P and H.P
b) perpendicular to V.P
c) perpendicular to H.P
d) inclined to H.P

Explanation: When the axis is perpendicular to the H.P., then the top view projection is the true shape and size of the base. Hence drawing top view will be the easiest and so it should be drawn first. From the top view front view is projected.

6. Which of the following statements is true with respect to the following projection? a) Cone with the base perpendicular to V.P and H.P
b) Pyramid with the base perpendicular to V.P
c) Triangular prism with the base parallel to H.P
d) Cone with base inclined to H.P

Explanation: In the given projection top view is equilateral triangle which is the base with true shape and size, hence the base is parallel to H.P., the given projection is of a triangular prism.

7. Which of the following statements is true with respect to the following projection? a) Cone with the base perpendicular to V.P and H.P
b) Triangular prism with the base parallel to V.P
c) Pyramid with the base parallel to H.P
d) Cone with base inclined to H.P

Explanation: In the given projection front view is equilateral triangle which is the base with true shape and size, hence the base is parallel to V.P., the given projection is of a triangular prism.

8. Find the type of solid from the given projection? a) Cone
b) Triangular prism
c) Pyramid
d) Tetrahedron

Explanation: In the given projection equilateral triangle is the shape of the top and front view, it is possible in the case of a tetrahedron.

9. Find the type of solid from the given projection. a) Cone
b) Triangular prism
c) Pyramid
d) Tetrahedron

Explanation: In the given projection, the top view is a rectangle and the front view is an equilateral triangle, which is possible in the triangular prism.
