# Mass

Sliding mass with inertia

# Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Sliding mass with inertia, without friction and two rigidly connected flanges.

The sliding mass has the length L, the position coordinate s is in the middle. Sign convention: A positive force at flange flange_a moves the sliding mass in the positive direction. A negative force at flange flange_a moves the sliding mass to the negative direction.

# Parameters (3)

L Value: 0 Type: Length (m) Description: Length of component, from left flange to right flange (= flange_b.s - flange_a.s) Value: Type: Mass (kg) Description: Mass of the sliding mass Value: StateSelect.default Type: StateSelect Description: Priority to use s and v as states

# Connectors (2)

flange_a Type: Flange_a Description: Left flange of translational component Type: Flange_b Description: Right flange of translational component
