First Year Engineering (Semester 1)

Total marks: 80
Total time: 3 Hours INSTRUCTIONS
(1) Question 1 is compulsory.
(2) Attempt any three from the remaining questions.
(3) Draw neat diagrams wherever necessary.

1.a. The point A of line AB is in H.P and 15 mm in front of V.P. Its front view and top view makes 51° and 48° with H.P. and V.P. respectively. Draw the projections of line AB if projector distance between end points of the line is 41 mm. Find its true length, true inclinations and locate its traces.

(12 marks) 00

2.a A hexagonal plate of 35 mm side is resting on one of its corner on the H.P. Draw projections of the plate when the plate surface makes an angle of 35° to H.P. and the diagonal passing through resting corner makes 22° inclination to V.P.

(12 marks) 00

3.a. A hexagonal prism of base 35 mm and height 85 mm is resting on one of its base corners. The vertical edge passing through the resting corner makes 45° inclination to H.P. Draw projections of the prism when the axis makes 22° inclination to V.P.

(13 marks) 00

4.a. Draw a parabola of 100 mm height and 150 mm base.

(7 marks) 00
