Similar to Example 4.5, Page 4.8 of EG - Basant Agrawal, TMH.

Unit-II
3. The top view of line AB, 70 mm long measures 55 mm and front view measures 45 mm. Its end A is 10 mm from H.P. and 15 mm from V.P. Draw the projections of the line and determine its inclination with the H.P. and V.P. Also draw its traces if the line is in first quadrant. 20 Marks
Similar to Example 7.26, Page 7.33 of EG - Basant Agrawal, TMH.
OR
4. Two bulbs on two poles are respectively 2 m and 3 m above the ground and 1 m and 2 m from the wall, 0·3 mm thick but on opposite side of it The distance between the bulbs measured along the ground and parallel to the wall is 3 m. Determine the real distance between the bulbs. 20 Marks
Similar to Example 7.61, Page 7.72 of EG - Basant Agrawal, TMH.

Unit-III
5. a) A hexagonal plate of 30 mm side is resting on one of its comer on H.P. The plate is perpendicular to V.P. and inclined to H.P. at 45°. Draw its projections. 10 Marks

Unit-IV
7. a) A cylinder of 45 mm dia. and 70 mm long is resting on one of its bases on H.P. It is cut by a section plane inclined at 60° with H.P. and passing through a point on the axis at 15 mm from one end. Draw the two views of the solid. Also obtain the true shape of the section. 10 Marks
Refer Example 10.12, Page 10.16 of EG - Basant Agrawal, TMH.
7. b) A pentagonal pyramid of side of base 30 mm and axis 60 mm long is resting on its base on H.P. with an edge of the base parallel to V.P. Draw the development of the lateral surface of the pyramid. 10 Marks
Similar to Example 11.18 Page 11.17 of ED - Basant Agrawal, TMH.
OR
8. a) A square prism with edge of base 45 mm and axis 90 mm long has its axis parallel to both H.P. and V.P. The lateral surfaces are equally inclined to H.P. It is cut by a vertical section plane inclined at 60° to the V.P. and passing through the axis at 65 mm from one end. Draw the projection of the solid. 10 Marks
Similar to Example 10.28, Page 10.32 of EG - Basant Agrawal, TMH.
8. b) Draw the development of the frustum of a hexagonal pyramid of side of base 35 mm at the bottom and 15 mm at the top, the height of the frustum being 50 mm. 10 Marks
