First Year Engineering (C Cycle) (Semester 1)
TOTAL MARKS: 100
TOTAL TIME: 3 HOURS (1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks. 1(a)(i) A point 30 mm above XY line is the front view of two pints A & B . The top view of A is 40 mm behind VP & The top view of B is 45 mm in front of VP . Draw the projections of the points & state the quadrants in which the points are situated.(10 marks) 1(a)(i) The font view of a 90 mm long line which is inclined at 45° to the XY line ,measures 65 mm . End A is 15 mm above the XY line and is in VP . Draw the projections of the line and find its inclinations with HP and VP.(20 marks) 1(b) A rectangular plate of negligible thickness of size 35 mm x 20 mm has one of its shorter edges in VP with that edge inclined at 40° to HP. Draw the top view if its front view is a square of side 20 mm.(30 marks) 2 A hexagonal prism 25 mm sides of base and 50 mm axis length rests on HP on one of its corners of the base such that the two base edges containing the corner on which it rests make equal inclinations with HP . Draw the projections of the prism when the axis of the prism is inclined to HP at 40°and appears to be inclined to VP at 457deg;(40 marks) 3(a) A vertical cylinder of base diameter 45 mm and axis length 60 mm is cut by a plane perpendicular to VP and inclined at 50° to HP , is passing through the center point of the top face . Draw the development of the lateral surface of the cylinder .(30 marks) 3(b) A frustum of cone of base diameter 50 mm, top diameter 25 mm and height 50 mm is placed centrally on a cylindrical slab of diameter 100 mm and thickness ? 30 mm Draw the isometric projection of the combination of the solids (30 marks)
