Degree of freedom

- The degree of freedom is defined as the number of independent motions (both
**translation and rotational**) a body can have. - The figure shows a rigid body in space. if there is no constraint on the body, then it can describe the following independent motions:
- Translation motions along x, y, and z-axis
- Rotational motion about these axes
- Thus the above body is having six independent motions. This body is said to have six degrees of freedom.
- Mathematically degree of freedom of a body in space is given as,
**Degree of freedom = 6 - Number of constraints**- Therefore,
**Degree of freedom = 6 - 5 = 1**
