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 is 35mm below HP, 15mm behind VP and 25mm behind / in front/ from RPP.Draw its projections and name the side view.(10 marks) 1(a)(ii) The top viw of a 75 mm long line AB measures 65mm, while the front view is 50mm .Its one end Ais in the H.P and 12mm in front of the V.P. Draw the projections of AB and determine its inclinations with the H.P and the V.P.(20 marks) 1(b) A rectangular lamina of 35 mm x 20 mm rests on HP on one of its shorter edges. The lamina is rotated about the edge on which it rests till it appears as a square in the top view .The edge on which the lamina rests is inclined 30° to VP. Draw its projections and find its inclination to HP.(30 marks) 2 A Hexagonal pyramid 25 mm sides of base and 50 mm axis length rests on HP on one of its edges of the base which is inclined to VP at 30°. Draw the projections of the pyramid when the axis is inclined to HP at 45°.(40 marks) 3(a) A square pyramid base 40 mm side and axis 65 mm ling has its base on HP and all the edges of the base are equally inclined to V P. It is cut to with an inclined section plane so as the truncated surface at 45° to its axis, bisection it. Draw the development of the truncated pyramid(30 marks) 3(b) A rectangular slab base ? 100 mm x 80 mm and height 30 mm ahs full depth co- axial square hole side-40mm , such that one of the sides of the square is parallel to one of the sides of the rectangle. Draw the isometric projection of the combination(30 marks)
