Question

A circle is placed perpendicular to vertical plane and inclined to horizontal which of the following is true?

(a) Front view-line, top view- circle

(b) Front view- circle, top view- circle

(c) Front view –line, top view-line

(d) Top view- ellipse, side view- ellipse

I got this question in an interview for job.

The query is from Projection of Planes Inclined to one of the Reference Plane & Perpendicular to other in chapter Projection of Planes of Engineering Drawing

Answer 1

Right option is (d) Top view- ellipse, side view- ellipse

For explanation: When a plane is perpendicular to one of the reference planes and inclined to the other, its inclination is shown by an angle which its projection on the plane to which it is perpendicular, makes with xy. Its projection on the plane to which it is inclined, is smaller than the plane itself.
