Examples
As shown at right, a simple pendulum is a system composed of a weight and a string. The string is attached at the top end to a pivot and at the bottom end to a weight. Being inextensible, the string’s length is a constant. Therefore, this system is holonomic; it obeys the holonomic constraint
where is the position of the weight and is length of the string.
The particles of a rigid body obey the holonomic constraint
where, are respectively the positions of particles and, and is the distance between them.
