Construct a hyperbola when the distance between the focus and directrix is 40mm. Eccentricity e = 4/3. Draw a tangent and a normal at any point on the curve.

Construct an ellipse when the distance between the focus and directrix is 30mm. Eccentricity e = 3/4. Draw a tangent and normal at any point on the curve.

A coir unwounded from a drum of 30 mm diameter. Draw the locus of the free-end of the coir for unwinding through an angle of 360˚. Also, draw the normal and tangent at any point on the curve.

A line PQ 75 mm long is inclined at angle of 45˚ to HP and 30˚ to VP. The point P is 15 mm above HP and 20 mm in front of VP. Draw the projections of the line.

A line AB 60 mm long has its end A 20 mm above HP and 25 mm in front of VP. End B is 40 mm above HP and 65 mm in front of VP. Draw the projections of AB and find the inclinations with HP and VP.

A rectangular lamina of size 60mm x 30mm is seen as a square in the top view when it rests on one of its edges on HP and perpendicular to VP. Draw the projections of the lamina. Find the true inclinations of its surface with HP. Draw the front view of the lamina when the edge about which it is tilted is inclined at angle of 45˚ to VP.

A pentagonal prism, side of face 25 mm and axis 50 mm long, is rested in one of its shorter edges on HP such that the base containing that edge makes an angle of 30˚ to HP and its axis is parallel to VP. Draw its projections.

A hexagonal prism, side of base 25 mm and axis 50 mm long, rests with one of its base corners on HP such that the base makes an angle of 60˚ to HP and its axis is parallel to VP. Draw its projections.

Draw the projection of a cylinder of diameter 40mm and axis 70mm long when it rests on HP on one of its base points. The axis of the cylinder is parallel to VP and inclined at an angle of 30˚ to HP. Draw its projections.
