Question

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

(a) triangle, triangle

(b) irregular shape of circle and triangle, triangle

(c) circle, irregular shape of circle and triangle

(d) circle, triangle

This question was posed to me by my school principal while I was bunking the class.

My doubt is from Projection of Solids with Axis Inclined to Horizontal Plane and Parallel to Vertical Plane in portion Projection of Solids of Engineering Drawing

Answer 1

Right choice is (c) circle, irregular shape of circle and triangle

Easiest explanation: For given positions of solid the solid is just tilted to some angle with H.P and previously given the axis is perpendicular to H.P so the top view gives the triangle and next with some given angle shape will change to irregular shape of circle and triangle.
