Question

The front views of 1^st, 2^nd and final stages of square prism, has its axis inclined at 45 degrees with H.P and has an edge of its base on H.P and inclined 30 degrees with V.P while drawing orthographic projections are _______________

(a) Rectangle, rectangle, hexagon

(b) Square, rectangle, rectangle

(c) Rectangle, rectangle, octagon

(d) Square, rectangle, hexagon

The question was posed to me by my school teacher while I was bunking the class.

This key question is from Projection of Solids with Axes Inclined to both Horizontal and Vertical Plane topic in section Projection of Solids of Engineering Drawing

Answer 1

The correct choice is (a) Rectangle, rectangle, hexagon

Explanation: As the 1^st stage is to keep the solid in simple position and given is front view it is rectangle and then rotated to an angle of 45 degrees with H.P which again gives rectangle and then rotating 30 degrees with V.P which gives an irregular hexagon.
