Question

A cube is placed on H.P on its base and vertical face is making 30 degrees with V.P, section plane is perpendicular to V.P the section will give a shape of a ___________

(a) triangle

(b) rectangle

(c) trapezium

(d) parallelogram

The question was posed to me in a job interview.

I'm obligated to ask this question of Sections of Prisms in portion Section of Solids of Engineering Drawing

Answer 1

Correct answer is (c) trapezium

For explanation: Prisms are obtained by extruding required shape up to some appreciable length so there will be same cross-section along the length perpendicular to axis. If the cutting plane is parallel to axis we get rectangle if inclined to axis the section depends on the position where it is cutting.
