1(a) Calculate the RF of a scale which measures 1.25 inches to a mile. Draw a comparative scale of kilometers to read up to 10 km. 1 mile=1.61 km. [8]
Refer attached supplementary problems of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
R.F.=1.25/(8×10×22×3×12)=1/50688
Length of kilometre (metric) scale, Ls (km)=19.7 cm
Let mile (US) scale is long enough to measure 7 miles. Therefore, length of mile scale, Ls (mile)=22.2 cm
(b) Trace the locus of the point on the circumference of the rolling circle of 40 mm diameter rolling on a circle of same diameter for one complete revolution. Name the curve. [7]
Refer Problem 6.9, Figure 6.9, page 6.9 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
2. A 75 mm long line AB has its end A 15 mm above the H.P. and 30 mm in front of the V.P. The front and top views make 45˚ and 60˚ respectively with the reference line. Draw its projections and determine its true inclinations with the reference planes. [15]
Refer attached supplementary problems of Engg. Drawing for JNTU-H by Basant Agrawal,TMH
3. A hexagonal plane with 35 mm side is resting on a side on the H.P., and inclined at 45˚ to the V.P. The surface of the plane is inclined at 30˚ to the H.P. Draw its projections using auxiliary plane method. [15]
Refer Exercise 10c, Question 2, page 13.38 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
4. A cone with a 60 mm base diameter and a 70 mm axis is resting on its base in the H.P. A section plane perpendicular to both the H.P. and V.P. cuts the cone at a distance of 12 mm from the axis. Draw the development of the retained cone. [15]
Refer Exercise 13a, Question 8, page 13.37 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
5. A cylinder resting on its base on the H.P. is penetrated by another cylinder with their axes bisecting at right angles. Draw the projections of the combination and show the curves of intersection. Consider the vertical cylinder having a 60 mm base diameter while the penetrating cylinder has a 50 mm base diameter.[15]
Refer Exercise 14, Question 10, page 14.27 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
6. A hexagonal prism having base with a 30 mm side and a 70 mm long axis is resting on its base on the H.P. with a side of base parallel to the V.P. It is cut by an A.I.P. making 45˚ with the H.P. and bisecting the axis. Draw its isometric projection. [15]
Refer Exercise 15b, Question 9, page 15.23 of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
7. Draw the front view, top view and right hand side view of the object whose isometric view is shown in the Figure 3 below (All dimensions are in mm). [15]
Refer attached supplementary problems of Engg. Drawing for JNTU-H by Basant Agrawal, TMH
8. Draw the perspective view of a square pyramid having base with a 40 mm side and a 60 mm long axis, resting on its base in the GP with its axis at a distance of 40 mm behind the PP and all the edges of the base equally inclined to it. 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]
