Different Problems & Solutions on Chapter: Projection of Planes

Problem 5.10 Projection of Planes – An isosceles triangle plate ABC having its base 50 mm and altitude 90 mm resting on H.P. on its base. The isosceles triangle is inclined at an angle 40° to the H.P. And the altitude in the top view is inclined at the angle 60° to the V.P. Draw the projections.

Problem 5.9 Projection of Planes – A circular plate of diameter 80 mm is resting on a point of its periphery on H.P. such that it makes an angle of 40° to the H.P. And the diameter passing through the point of its resting on H.P. makes an angle of 60° with V.P. Draw the projections of it.

Problem 5.8 Projection of Planes – A pentagonal plate of side 60 mm is held on V.P. on one of its corner. The edge opposite to that corner makes an angle of 25° with the H.P. The flat surface of pentagon is inclined at 40° to the V.P. Draw the projections.

Problem 5.7 Projection of Planes – A square lamina of side 80 mm rests on a corner on H.P. and it is inclined with H.P. such that its plan is a rhombus with a diagonal of 40 mm. The long diagonal is inclined with the V.P. at 45°. Determine its inclination with H.P. and draw it’s projections.

Problem 5.6 Projection of Planes – An elliptical plate of dimension 140 mm X 80 mm rests on a point of its periphery on H.P. and inclined with it such that its plan is a circle. Draw the projection and find out the inclination of it with H.P.
