Before going into this, it will be more genuine and meaningful if we have a
short idea about what is degree of freedom. Degree of freedom: The number of
independent co-ordinates required for describing/illustrating or determining the
motion/movement or vibration of a system is known as degree of freedom. The
rigid block foundation is designed to have six degree of freedom. Thus, it means
any displacement or movement can be resolved into six independent displacements
which are as follows;1. Translation along X-axis
3. Translation along Y-axis
5. Translation along Z-axis
7. Rotation about X-axis
9. Rotation about Y-axis and
11. Rotation about Z-axis.The translation along Z-axes and rotation about Z-axis
may take place independently to any other motions. But, translations and
rotation about X & Y-axis are coupled/joined since these cannot happen or take
place independent to one another. The X, Y and Z-axes are also known as
pitching, rocking and yawing axes.
