Ls=16 cm
(b) Draw a circle of 40 mm diameter. The diameter AB is vertical with end A at top. Trace the curve generated by the end A when the circle rolls without slipping on a horizontal line for three-fourth rotation and then on the vertical line for its next half rotation. Name the curve traced by end A. [7]
Refer Problem 5.1, figure 5.12, page 5.6-5.7 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
2. The end A of an 80 mm long line AB is 20 mm above the H.P. and B is 15 mm in front of the V.P. The line is inclined at 30˚ to the H.P. and its top view makes 60˚ with the V.P. Draw its projections and find its inclination with the V.P. [15]
Refer Exercise 9c, Question 10, page 9.58 of Engg. Drawing for JNTU-H by Basant Agrawal,TMH
3. A square pyramid, with a base having a 50 mm side and a 60 mm long axis, has one its triangular face on the H.P. and a slant edge containing that face is parallel to the V.P. Draw its projections. [15]
Refer Exercise 11c, Question 4, page 11.49of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
4. A cylinder with a 50 mm base diameter and a 70 mm long axis is resting on its base in the H.P. It is cut by an auxiliary inclined plane whose V.T. is inclined at 30˚ with the H.P. and passes through top end of one of the extreme generators. Draw the development of the lateral surface of the retained solid. [15]
Refer Exercise 13a, Question 4, page 13.36 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
5. A triangular prism, having base with a 60 mm side and a 100 mm long axis, is resting on its base on the H.P. with a nearer face parallel to the V.P. It is penetrated by a cylinder with a 50 mm diameter and a 90 mm long axis. The axis of the cylinder is parallel to both the reference planes and 15 mm away from the axis of the prism towards the observer. Draw the projections of the combination and show the curves of intersection. [15]
Refer Exercise 14, Question 9, page 14.27 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
6. Draw the isometric projection of a frustum of a sphere with a 60 mm diameter, frustum circle with a 40 mm diameter, resting centrally on a cube with a 50 mm side such that the circle of the frustum is horizontal and does not touch the cube. [15]
Refer Exercise 15b, Question 8, page 15.23 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
7. Draw the front view, top view and side view of the object whose isometric view is shown in the Figure 2 below (All dimensions are in mm). [15]

8. Draw the perspective view of a hexagonal prism having a base with a 40 mm side and a 60 mm long axis, resting on its base in the GP with a side of base parallel to and 10 mm behind the PP. The station point is 50 mm in front of the PP, 75 mm above GP, and lies in a CP which is at a distance of 50 mm towards the right of the axis. [15]
