Q.2) Fig – II (b) A cone of base 60 mm diameter axis 70 mm long is resting on its base on ground. It is cut by an auxiliary

inclined plane inclined at 450

to HRP and interesting the axis 30 mm above the base. Draw the sectional top view, true

shape of section and development of its lateral surface

Q.3) A right regular cone of 75 mm diameter and having an axis of 90 mm length, rests with its base in HP. A square hole of 30

mm sides is made in the truncated cone such that the axis of the square hole is perpendicular to the VP and passes through

a point on the cone axis, 25 mm above the HP. The sides of the square hole are all inclined equally to the HP. Draw the

development of the surface of the truncated cone.
