degree of freedom

degree of freedom
in the simplest of cases, a degree-of-freedom is an independent displacement or rotation that a system may exhibit. A degree-of-freedom for a system is analogous to an independent variable for a mathematical function. All system degrees-of-freedom must be specified to fully characterize the system at any given time. The number of degrees of freedom of a vibrating system is the sum total of all ways in which the masses of the system can be independently displaced from their respective equilibrium positions. Examples: a single rigid body constrained to move only vertically on supporting springs is a system of one degree of freedom. if the same mass is also permitted angular displacement in one vertical plane, it has two degrees of freedom; one being vertical displacement of the center of gravity; the other, angular displacement about the center of gravity.
