Mass

Sliding mass with inertia

 Description The Mass component models a fixed mass with two rigidly connected translational flanges. The mass is centered between the flanges.
 Equations $ma={f}_{a}+{f}_{b}$ $a=\stackrel{.}{v}$ $v=\stackrel{.}{s}$ ${s}_{a}=s-\frac{1}{2}L$ ${s}_{b}=s+\frac{1}{2}L$

Variables
