Answer any FIVE Questions
1. (a) Inscribe an ellipse in a parallelogram having sides 150mm and 100mm long
and an inclined angle of 1200.
(b) Draw a rectangle having its sides 125mm and 75mm long. Inscribe two parabo-
las in it with their axis bisecting each other.
2.A circle of 50mm diameter rolls on the circumference of another circle of 175mm
diameter and outside it. Trace the locus of a point on the circumference of the
rolling circle for one complete revolution. Name the curve. Draw a tangent and a
normal to the curve at a point 125mm from the center of the directing circle.
3.Draw the projections of the following points on the same ground line, keeping the
Projectors 20mm apart.
(a) Point C, in the V.P. and 40mm above the H.P.
(b) Point D, 25mm below the H.P. and 25mm behind the V.P.
(c) Point E,15mm above the H.P. and 50mm behind the V.P.
(d) Point F, 40mm below the H.P. and 25mm infront of the V.P.
4. A line measuring 75mm long has one of its ends 50mm in front of V.P. and 15mm
above H.P. The top view of the line is 50mm long. Draw and measure the front
view. The other end is 15mm in front of V.P. and is above H.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 a pentagonal pyramid, base 30 mm edge and axis
50mm long, having its base on the H.P. and an edge of the base parallel to
the V.P. Also draw its side view.
(b) Draw the projections of a hexagonal pyramid, base 30 mm side and axis 60
mm long, having its base on the H.P. and one of the edges of the base inclined
at 450 to the V.P.
(c) A square pyramid, base 40mm side and axis 65mm, long has its base in the
V.P. One edge of the base is inclined at 300 to the H.P. and a corner contained
by that edge is on the H.P. Draw its Projections.
7.Draw the isometric view of a Door-Steps having three steps of 22cm tread and 15cm
rise. The steps measure 75cm widthwise.
8. Draw the following views of the block shown in figure 8. All dimensions are in mm.
- Front View.
- Top view
- Both side views.
