Steps are given to determine the centre of curvature at a given point on a hyperbola. Arrange the steps. Let P be the given point on the conic, V is vertex and F and F1 are the foci. i. Draw a line GO parallel to HF and cutting the axis at O. ii. Draw a line F1G inclined to the axis and equal to FV1. iii. Then O is the centre of curvature at the vertex V. iv. On F1G, mark a point H such that HG = VF. Join H with F.

Topics in this quiz include: Conic sections basics, evolutes and helix construction, cam, helical springs and screw threads construction.   Here are some curves used in engineering drawing: Conic section: A quadratic curve that results from a plane intersecting a cone's surface. The three types of conic sections are the hyperbola, the parabola, and the ellipse. Cycloid: The path of a point on a circle that moves along a straight line without slipping. Ellipse: The locus of all points in a plane where the sum of their distances from two fixed points is constant. The fixed points are known... Show more

Here are some curves used in engineering drawing:
Conic section: A quadratic curve that results from a plane intersecting a cone's surface. The three types of conic sections are the hyperbola, the parabola, and the ellipse.
Cycloid: The path of a point on a circle that moves along a straight line without slipping.
Ellipse: The locus of all points in a plane where the sum of their distances from two fixed points is constant. The fixed points are known as the foci, and the fixed line is the directrix.
Compound curve: A curve made up of two or more circular curves that are connected end to end with different radii and centers. Compound curves are used when a more gradual transition between straight sections is required.
Reverse curve: A curve made up of two circular curves with opposite directions. Reverse curves are used when a significant change in alignment direction is needed. 

Other curves used in engineering drawing include: Involute, Evolute, Spiral, Helix.
