Question

A square is placed perpendicular to vertical plane and inclined to horizontal plane which of the following is true. H.T is horizontal trace and V.T is vertical trace?

(a) H.T- inclined to xy, V.T- perpendicular to xy

(b) H.T- inclined to xy, V.T- perpendicular to xy

(c) H.T- perpendicular to xy, V.T- inclined to xy

(d) H.T- parallel to xy, V.T- perpendicular to xy

The question was asked by my college director while I was bunking the class.

I would like to ask this question from Projection of Planes Inclined to one of the Reference Plane & Perpendicular to other topic in portion Projection of Planes of Engineering Drawing

Answer 1

The correct option is (b) H.T- inclined to xy, V.T- perpendicular to xy

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.
