SECTION B (Marks: 8 each)
5. A vertical cylinder of 45 mm diameter and height 70 mm resting on its base on HP, is completely penetrated by another cylinder of same diameter and length . Their axes bisect each other at right angles and are parallel to VP. Draw their projections showing lines of interpenetration on two cylinders.
6. Draw the projections of a square pyramid of base edges 30 mm and axis 54 mm, resting on its base on HP with one base edges parallel to VP and axis perpendicular to the HP.
7. (a) A square prism of side 30 mm 40 mm height is resting on HP. A vertical square bore of 10 mm side is cut through its face reaching other square face of the prism. Draw the isometric projection ofthe prism.
8. An equilateral triangle of 30 mm sides has a corner in VP and 20 mm away for HP. Draw its projections and traces when the plane is parallel to the HP and one of its sides inclined at 45° to the VP.
9. A pentagon prism of 25 mm base edges and 50 mm long, resting on its base with an edge of base at 45° to the VP. The prism is cut by a section plane V.T. inclined at 30° to the HP and passes through a point 25 mm from the base along its axis . Develop its lateral surface of the truncated prism.
