2. b) Draw a cycloid for one complete revolution of a circle having 50mm diameter.
7 Marks
Similar to Example 4.1, Page 4.2 of EG - Basant Agrawal, CM Agrawal - TMH.
Unit-II
3. a) A straight line PQ has its end P 20 mm above the H.P and 30 mm in front of V.P. The end Q is 80 mm above H.P. and 70 mm in front of V.P. If the end projectors are 60 mm apart, Draw the projections of the line. Determine its true length and true inclinations with the reference plane. 14 Marks

4. Draw the projections of straight line AB of l00 mm long when one of its ends is touching the V.P. and the other end touching H.P. The angle of inclination with H.P and V.P are 40° and 50° respectively. 14 Marks
Problem 17 Page 7.59 of EG - Basant Agrawal, CM Agrawal - TMH.
Unit-III
5. Draw the projections ofa cone, base 30 mm diameter and axis 50 mm long when it is resting on H.P. on a point of its base circle with the axis making an angle of 45° with H.P and 30° to V.P.
14 Marks
Refer Example 9.42, Page 9.49 of EG - Basant Agrawal, CM Agrawal - TMH.
OR
6. A pentagonal prism, having a base 35 mm side and a 70 mm long axis has its axis inclined at 30° to V.P. An edge of its base is in V.P. and inclined at 45° to the H.P. Draw its projections. 14 Marks
Example 9.36, Page 9.43 of EG - Basant Agrawal, CM Agrawal - TMH.
Unit-IV
7. A cone base 75 mm diameter and axis 80 mm long is resting on its base on the H.P. It is cut by a section plane perpendicular to the V.P. inclined at 45° to the H.P. and cutting the axis at a point 35 mm from the apex. Draw its front view sectional top view and true shape of the section. 14 Marks
Problem 11, Page 10.41 of EG - Basant Agrawal, CM Agrawal - TMH.
OR
8. A square pyramid side of base 30 mm and axis length 40 mm is resting on its base on H.P. with sides of base equally inclined to V.P. A circular hole of diameter 20 mm is drilled through the pyramid so that the axis of the hole is perpendicular to V.P., parallel to H.P. and intersecting the axis of the pyramid at 12.5 mm above the base. Develop the remaining portion of the pyramid. 14 Marks
This is a typical problem and one should refer Engineering Drawing 2e - Basant
Agrawal, CM Agrawal TMH for solution.
Unit-V
9. A glass bottle consists of a cylinder of 60 mm diameter and 40 mm height with a cylindrical neck of 20 mm diameter and 20 mm height. The bottle is fitted with a cork of 18 mm diameter which projects by 5 mm. Draw its isometric view. 14 Marks
