Class StatFequilibriumCmd

java.lang.Object

net.sf.drawj2d.cmd.statics.StatFequilibriumCmd

All Implemented Interfaces:

Command

public class StatFequilibriumCmd
extends java.lang.Object
implements Command

StatFequilibriumCmd implements the "stat.fequi", which equilibrates a known force F by two other forces A and B, of which the azimuth are known. The command returns the force A. Equilibrium is defined F + A + B = 0, thus B is [--- "[XY $F] 0 0" $F $A] resp. [stat.equi $F $B] Kraftdreieck für das Kräftepolygon F+A+B=0: Bekannt sind F (effektiv genügt F.kraft), sowie die Richtungen von A und B [in Degrees]. Gesucht sind die Kraftkomponenten von A (und B). Die Funktion gibt die Kraft A zurück. B ergibt sich aus [--- "[XY $F] 0 0" $F $A] resp. [stat.equi $F $B]
