Basic Kinematics of Constrained Rigid Bodies Rapid Design through Virtual and Physical Prototyping Introduction to Mechanisms Yi Zhang with Stephannie Behrens 4 4.1 4.1.1 The degrees of freedom (DOF) of a rigid body is defined as the number of independent movements it has. Figure 4-1 shows a rigid body in a plane. To determine the DOF of this body we must consider how many distinct ways the bar can be moved. In a two dimensional plane such as this computer screen, there are 3 DOF.

The bar can be translated along the x axis, translated along the y axis, and rotated about its centroid. Figure 4-1 Degrees of freedom of a rigid body in a plane 4.1.2 An unrestrained rigid body in space has six degrees of freedom: three translating motions along the x, y and z axes and three rotary motions around the x, y and z axes respectively.
