TOTAL MARKS: 80
TOTAL TIME: 3 HOURS (1) Question 1 is compulsory.
(2) Attempt any three from the remaining questions.
(3) Assume data if required.
(4) Figures to the right indicate full marks. 1(a) A circle of 60mm diameter rolls on a straight line without slipping. Draw the locus of a point 'P' for complete revolution of the circle. The point 'P' is 38mm above the straight line and towards the right of vertical centre line of the circle.
(6 marks) 1(b) Figure 1 shows pictorial view of an object Draw :
(i) Front view
(ii) Top view
(iii) Dimension the views

(9 marks) 2 A pentagonal pyramid of 29mm. Edge of base and 60 mm length of axis has a 28mm. Edge on the H.P. The axis is inclined at 35°(15 marks) 3 Figure 2 shows pictorial view of an object Draw :
(i) Sectional Front View along A-A
(ii) Sectional Left hand side view along B-B
(iii) Top View
Dimension the views (any four)

(15 marks) 4(a) The distance between the end projectors of a line AB is 60mm. The end A is 25mm above H.P. and 45mm in front of V.P., while the order end B is 60mm above H.P. and 15mm in front of V.P. Draw projections and find the true length and also inclination of the line with H.P. and V.P.(9 marks) 4(b) Figure 3 shows two views of an object. Draw isometric view of the object.

(6 marks) 5 A square pyramid of base side 25mm and altitude 50mm rests on its base on the HP with two sides of the base parallel to VP. It is cut by a plane bisecting the axis and inclined at 30° to the base. Draw front view, sectional top view and true shape of the section. Also draw the development of the lower part of the pyramid.(15 marks) 6(a) A cylinder with 50mm diameter of its base and axis measuring 70mm has its axis inclined at 30°(6 marks) 6(b) Draw isometric projection using natural scale. Refer Figure No.4
