Answer any FIVE Questions
1. Draw a straight line AB of any length. Make a point F, 65mm from AB .Trace
the paths of a point P moving in such a way that the ratio of its distance from the
point F, to its distance from AB is (a) 1 (b) 2:3
Plot at least 8points. Name each curve. Draw a normal and a tangent to each
curve at a point on it 45 mm from F.
2.A circle of 35mm diameter rolls on a horizontal line. Draw the curve traced out by a
point R on the circumference for one half revolution of the circle. For the remaining
half revolution, the circle rolls on the vertical line. The point R vertically above
the center of the circle in the starting position.
3.(a) Draw the projections of the following points on the same ground line, keeping
the Projectors 25mm apart.
i. A, in the H.P. and 20 mm behind the V.P.
ii. B, 40mm above the H.P. and 25mm in front of the V.P.
(b) State the quadrants with the help of drawing, in which the following points
are situated
i. A point P; its top view is 40mm above xy; the front view 20 mm below
the top view.
ii. A point Q; its projections coincide with each other 40mm below x y.
4. The length of the top view of a line is 40mm and the length of the front view is
50mm, the top view is inclined at 300 to xy. Draw the projections of the line,
assuming that its one end is situated on H.P. and 25mm in front of V.P. Determine
the inclinations of the line with H.P and V.P.
5. A regular pentagon of 30mm side, is resting on one of its edges on H.P. which is
inclined at 450 to V.P. Its surface is inclined at 300 to H.P. Draw its projections.
6. (a) Draw the projections of
i. a cylinder, base 40 mm diameter and axis 50 mm long, and
ii. a cone, base 40mm diameter and axis 50mm long,
resting on the H.P. on their respective bases.
(b) A hexagonal prism has one of its rectangular faces parallel to the H.P. Its axis
is perpendicular to the V.P. and 3.5 cm above the ground. Draw its projections
when the nearer end is 2 cm in front of the V.P. Side of base 2.5cm long, axis
5 cm long.
(c) A cube of 40mm side rests with one of its square faces on the H.P. such that
one of its vertical faces is perpendicular to V.P. Draw its projections. The
nearest edge parallel to V.P. is 5mm in front of it.
7.(a) Draw the isometric view of a square prism, with side of base 40mm and length
of axis 70mm, when its axis is
i. vertical and
ii. horizontal.
(b) Figure 7b shows the front view of a sphere, resting centrally on the top of a
square block. Draw the isometric projection of the arrangement all dimensions
are in mm.
8. Draw the following views of the block shown in figure 8. All dimensions are in mm.
- Front View.
- Top view
- Both side views.
