of intersection.

Problem No. – 27 (GTU EXAM_2015) A cylinder 50mm diameter is rest on HP is cut by another cylinder diameter 20mm, its

axis is parallel to VP and makes an angle of 45º with HP. Draw the front view showing

the line of intersection.

Problem No. – 28 (GTU EXAM_2015) A square prism 40 mm side and 80 mm height is resting on HP and its vertical face is

inclined 45º to VP is cut by another square prism 20mm side and 60 mm height its face

is inclined 45º to HP axis of both the prism is intersecting at right angle. Draw the front

view showing the line of intersection.

Problem No. – 29 (GTU EXAM_2015) A cylinder 50mm diameter is rest on HP is cut by another square prism 20mm side its

face is inclined equally inclined to HP and VP axis of both cylinder and prism is

intersecting at right angle. Draw the front view showing the line of intersection.

Problem No. – 30 (GTU EXAM_2015) A cylinder, diameter of base 50 mm and height of axis 70 mm, rests on HP on its base

rim such that its axis is inclined at 450 to HP and top view of the axis is inclined at 600 to

the VP. Draw its projection.

Problem No. – 31 (GTU EXAM_2016) A cylinder of base diameter 60 mm and 90 mm long, resting on its base on HP. It is

penetrated by a square prism of 36 mm base sides and 90 mm long such that axis of the

solids bisects each other at right angles. The faces of prism are equally inclined with

V.P. Draw the projections of solids showing the line of intersection.

Problem No. – 32 (GTU EXAM_2016) A cylinder of base diameter 54 mm and height 100 mm, resting on its base in HP. It is

penetrated by another cylinder of base diameter 40 mm. The axis of penetrating

cylinder is inclined to HP at 45˚, is parallel to VP and cuts the axis of vertical cylinder at

a distance of 20 mm from its base. Draw projections of two cylinders showing the line

of intersection. Assuming suitable length of penetrating cylinder.

Problem No. – 33 (GTU EXAM_2016) A circular cone base diameter 56 mm and height 66 mm, resting on its base on HP. It is

completely penetrated by a cylinder of base diameter 30 mm. The axis of cylinder is

parallel to both HP and VP and intersects the axis at a distance of 20 mm from its base.

Draw projections of solids showing the line of intersection. Assuming suitable length of

penetrating cylinder.
