WebThe human ankle performs two kinds of movement, flexion/extension and inversion/eversion, allowing two degrees of freedom. Ball-and-socket joints, such as the human hip, allow three degrees of freedom. Most animal joints have at least two muscles (an antagonistic pair) for each degree of freedom. WebDegrees of freedom A joint which moves substantially in one plane (like an elbow) is uniaxial. One which moves in two planes is biaxial, one which moves in three is triaxial. A ball and socket is multiaxial, but is equivalent to a triaxial as it has three degrees of freedom i.e. all movements can be reduced to XYZ axes.

WebThey differ from each other by the number of degrees of freedom per joint. A degree of freedom refers to the direction in which the joint can move or rotate. Two-dimensional plane frame members have three degrees of freedom per joint displacement in the global X direction, displacement in the global Y direction, and rotation about the global Z ...
