Question

A regular cone first placed in such a way its axis is perpendicular to V.P and next this is tilted such that its base is making some acute angle with V.P. The top view for previous and later one will be.

(a) Triangle, triangle

(b) irregular shape of circle and triangle, triangle

(c) triangle, irregular shape of circle and triangle

(d) circle, triangle

This question was addressed to me during an interview.

Enquiry is from Projections of Solids with Axis Inclined to Vertical Plane and Parallel to Horizontal Plane topic in chapter Projection of Solids of Engineering Drawing

Answer 1

The correct answer is (a) Triangle, triangle

Easy explanation: For given positions of solid the solid is just tilted to some angle with V.P and previously given the axis is perpendicular to V.P so the top view gives the triangle and next with some given angle shape will not change.
