6.
Draw an ellipse having conjugate axis of 80mm and 40mm, making an angle
of 75° with each other. Determine the major and minor axis.

7.
A point P is at a distance of 40mm from one asymptote and 30mm from the
other. Draw a hyperbola passing through P if the angle between the
asymptotes is 75°

8.
The vertex and the focus of a hyperbola are at distances of 20 mm and
50mm respectively from a fixed straight line. Draw the tangent and
hyperbola and a normal at any point on it.

9.

10mm and a rise of 5 mm .Make out a profile of the bridge by offset
method.

10. Draw a four centered approximate ellipse having a major axis 120mm and minor axis 80 mm.

11.
A ball thrown up in the air reaches a maximum height of 50m.The
horizontal distance traveled by the ball is 80m.Trace the path of the
ball and name it. Find the direction of motion of the ball with
reference to the horizontal when the ball has reached a height of 40m
during the first half of the travel.

12. Draw a cycloid formed by a rolling circle 50mm in diameter. Use 12 divisions.

Draw a tangent and a normal at a point 30mm above the directing line.

13.

180mm. Draw the path described by a point on the circumference of the
rolling circle of one complete revolution. Draw a tangent and normal at a
point on the curve.

14.
