Answer ONE question from each Unit
UNIT - I [1 x 12 = 12M]
1) Construct an ellipse by concentric circles method when the major axis is 120 mm and the distance between the foci is 80 mm. determine the minor axis. (OR)
2) A circle of 50 mm diameter rolls along a straight line without slipping. Draw the curve traced by a point P on the circumference for one complete revolution of the circle. Name the curve.
UNIT - II [1 x 12 = 12M]
3) A line AB 65 mm long has its end A 20 mm above H. P and 25 mm in front of the V. P. The end B is 40 mm above the H. P and 65 mm in front of the V. P. Draw the projections of AB and show its inclinations with the H. P and V. P. also locate traces. (OR)
4) The front view of a 125 mm long line AB measures 75 mm and its top view measures 100 mm. Its end B and the mid point M are in the first quadrant, M being 20 mm from both the planes. Draw the projections of the line AB.
UNIT - III [1 x 12 = 12M]
5) A square lamina of 50 mm side rests on one of the corners on the H.P. The diagonal through that corner makes 300 to the V.P. The two sides containing this corner make equal inclination with the H.P. The surface of the lamina makes 450 to the H.P. Draw the front view and top view of the lamina. (OR)
6) A thin circular plate of 70mm diameter is resting on its circumference such that its plane is inclined 600 to the H.P and 300 to the V.P. Draw the projections of the plate.
UNIT - IV [1 x 12 = 12M]
7) Draw the projections of a hexagonal pyramid base 30 mm and axis 65 mm long resting on an edge of its base on the ground and inclined at 400 to VP. Its axis is inclined at 300 to HP. (OR)
8) Draw the projections of a cube of 25 mm long edges resting on the H.P, on one of its corners with a solid diagonal perpendicular to the V.P.
UNIT - V [1 x 12 = 12M]
9) Draw the isometric view of the object shown in figure below (attached as 'Image 1' in document). All dimensions are in mm. (OR)
10) Draw the front view, top view and side view of the object whose isometric view is shown in the figure below (attached as 'Image 2' in document). All dimensions are in mm.
