Stabsystem mit Verbindungsgelenk

Beitragvon dmn alex am Fr 15. Nov 2013, 16:02

Hallo,
ich bin neu im Forum und hoffe ich bin hier in der richtigen Unterkategorie gelandet. Ich habe eine Aufgabe bei der ich nicht weiterkomme:
Bild

momentan bin ich zu den folgenden Bilanzen gekommen:

FRVertikal= Fs1*cos alpha 1 + Fs2*cos alpha 2+ F1=0
FRHorizontal=-Fs1*sin alpha 1 + FS2 * sin alpha 2 + F2= 0

nun wollte ich die Billanzen nach einer unbekannten umstellen und dann gleichsetzen um folglich die zweite unbekannte zu ermitteln. Nur bekomme ich das leider nicht hin. Vielleicht kann mir da ja jemand weiter helfen!

LG dmn alex

einfach noch die Momentengleichung mit benutzen. Moment um Lager 1 danach Moment um Lager 2 und du bekommst die Kräfte in y-Richtung
