1 (Statistics) Any of the unrestricted, independent random variables that constitute a statistic.2. (Physics) Any of the minimum number of coordinates required to specify completely the motion of a mechanical system. Any of the independent thermodynamic variables, such as pressure, temperature, or composition, required to specify a system with a given number of phases and components
(Directions and rotations at which an object can move about its axes ) In Mechanical Desktop each time you add a constraint between two parts, one DOF (or more) is eliminated A fully constrained part cannot move in any direction The degrees of freedom symbol is displayed on the screen with one or two numbers in the circle For example, you might see 3-2 or 2-1, etc The first number indicates the order in which the part was instanced into the assembly Thus, if the number is a 3, it means that this was the third part instanced into the assembly
(DF) A mathematical concept that indicates the number of observations or values in a distribution that are independent of each other or are free to vary They are used with various measures such as t-tests to refine the results of treatments of probability or chance in determining statistical significance For example, if you have a distribution of three numbers that could vary but the sum of those numbers has to equal 100, then although you could select three numbers, in reality you only have to select two because the third number is determined by the first two numbers selected In this case, there are two independent values, or two degrees of freedom
a single way in which an arm can move A robot that could move up/down, left/right, and in/out would have 3 degrees of freedom The human arm (not counting the hand) has 7 degrees of freedom
(statistics) an unrestricted variable in a frequency distribution one of the minimum number of parameters needed to describe the state of a physical system
A single coordinate of relative motion between two bodies Such a coordinate is free only if it can respond without constraint or imposed motion to externally applied forces or torques For translational motion, a DoF is a linear coordinate along a single direction For rotational motion, a DoF is an angular coordinate about a single, fixed axis
