An inelastic string of 150 mm long, has its one end attached to the circumference of a circular disc of 40 mm diameter. Draw a curve traced out by the other end of the string, when it completely wound around the disc, keeping the string always tight. Name the curve. Also draw a tangent and normal to the curve through any point.
