Conical pendulum
Description
A conical pendulum is a weight (or bob) fixed on the end of a string (or rod) suspended from a pivot. Its construction is similar to an ordinary pendulum; however, instead of rocking back and forth, the bob of a conical pendulum moves at a constant speed in a circle with the string (or rod) tracing out a cone. The time required for the bob of the conical pendulum to travel one revolution depends on the horizontal circle’s radius and the angle between the leg and the hypotenuse.
