Construct a scale to measure km, 1/8 km and 1/40 of a km, in which 1 km is represented by 4 cm. Mark on this scale a distance of 2.775 km.
Draw the projections of the following points on the same ground lines, keeping the projectors 15 mm apart:
A person travels in a curved path such that 25 mm distances from a fixed straight line and fixed point remain the same. Construct the traced curvature path by person and name the curve.
A wheel rolls over the horizontal straight road and covers 220 mm distance in one rotation. Draw the path traced by the point P which is initially at the point of contact between the wheel and the road.
Draw an Archimedean spiral of 1½ convolutions, the greatest and least radii being 115 mm and 15 mm respectively. Draw a tangent and a normal to the spiral at a point 63 mm from the pole.
A line CD, 80 mm long is inclined at 45º to H.P. and 30º to the V.P., its end C is in H.P. and 40 mm in front of V.P. Draw the projections.
A hexagonal plane of 30 mm side, rests on the V.P. on an edge such that the surface is inclined at 45º to the V.P. Draw its projections.
A circular plane of 80 mm diameter has one of the ends of the diameter in the H.P. while the other end is in the V.P. The plane is inclined at 30º to the H.P. and 60º to the V.P. Draw its projections.
A 100 mm long line PQ is inclined at 30º to H.P. and 45º to the V.P. Its mid-point is 35 mm above the H.P. and 50 mm in front of V.P. Draw its projections.
The top view of a lamina whose surface is perpendicular to V.P. and inclined at an angle of 45º to H.P. appears as a regular hexagon of 30 mm side, having a side parallel to the reference line. Draw the projections of plane and obtain its true shape.
Draw the projections of a rhombus having 100 mm and 40 mm long diagonals. The bigger diagonal is inclined at 30º to H.P. with one of the end point in H.P. and the smaller diagonal is parallel to both the planes.
A square pyramid, side of base 40 mm and axis 60 mm is resting on its base on H.P. Draw its projections when (a) a side of the base is parallel to V.P., (b) a side of the base is inclined at 30º to
A hexagonal pyramid, 30 mm base side and 60 mm long axis rests on the H.P. with a side of base parallel to V.P. It is cut by planes perpendicular to V.P., to obtain the front view as shown in Fig. 1. Draw the development of the lateral surface of the retained solid.
A cylinder with 50 mm base diameter and 80 mm long axis, is lying on a generator on the H.P. with its axis parallel to the V.P. It is cut by an A.I.P. inclined at 30º to the H.P. and passes through a point on the axis 30 mm from one of its ends. Draw its anyone sectional top view.
