A coir rope is unwound from a drum of 40 mm diameter. Draw the locus of the free end of the rope for unwinding through an angle of $360^{\circ}$. Draw also a tangent and normal at any point on the curve.

Explanation

When a rope is unwound from a drum, the free end of the rope traces out a circle. The radius of the circle is equal to the radius of the drum, which is 20 mm. The tangent and normal at any point on the curve can be drawn using the properties of circles.
