SECTION B (Marks: 8 each)
5. A cylinder of 45 mm diameter and 60 mm long is resting on one of its bases on HP. It is cut by a section plane inclined at 60 degree with HP and perpendicular to VP passing through a point on the axis 15 mm from its top end. Draw its sectional top view, front view and sectional end view.
7. A right circular cone, diameter of base 50 mm and height 60.mm, resting on its base in HP, is completely penetrated by a cylinder of diameter 25 mm and 70 mm long. The axis of the penetrating cylinder is parallel to both HP and VP and intersects the axis of the cone at a distance of 20 mm from its base. Draw the projection of the solids showing curve of intersection.
8. A cylindrical slab 60 mm diameter and 20 mm thick is surmounted by a cube of 28 mm edge. On the top of a cube, rests a square pyramid, attitude 30 mm and side of base 15 mm. The axes of the two solids are in same straight line. Draw isometric projections of the solids.
9. Draw the following view of given figure (i) Front view (ii) Top view (iii) Left side view
