4th Order Point Mass (Longitudinal)
A model of planar translational motion of a material point.
Description
The 4th Order Point Mass (Longitudinal) block implements a model of planar translational motion of a material point.
The equations of motion have the form:
The 4th Order Point Mass (Longitudinal) block works in SI units.
|
The block uses coordinate systems according to the international standard ISO 1151. |
