8.3 Beam


Set a rigid body (a beam) composed by elements of beam. Not support forces, frictions or resultants. Starting from a horizontal beam, the left side is the vertex to measure the angle.

Equations:2 or 3. If all applied forces are vertical, are two equations (the sum of vertical forces and sum of moments). Isn’t allowed apply horizontal forces only, because FiscaLab assumes that the beam have a weight.
Name:Name of the beam.
m:Mass of the beam.
lc:Distance from the center of mass of the beam to the vertex point (the distance is measured along the beam).
ang:Angle of inclination of the beam, measured from the positive X axis. The positive sense is the opposite of clockwise.
