# Problem 5.10 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

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

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

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

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.

# Problem 5.5 Projection of Planes

Problem 5.5 Projection of Planes – A thin rectangular lamina of dimensions 100 X 50 mm is resting on its shorter side in the V.P. and inclined at 40° with the H.P., such that its front view is a square of side 50 mm. Draw projection of the lamina and find its inclination with the V.P.

# Problem 5.4 Projection of Planes

Problem 5.4 Projection of Planes – A regular hexagonal plate 35 mm side is resting on one of its corners in H.P. The diagonal through that corner is inclined at 350 to H.P. and the plan of that diagonal inclined to V.P. by 250. Draw the projection of the plate.

# Problem 5.3 Projection of Planes

Problem 5.3 Projection of Planes – A semi- circular thin plate of 60 mm diameter rest on the H.P. on its diameter which is inclined at 45˚ to the V.P. and the surface is inclined at 30˚ to the H.P. Draw the projection of the plate.
