Homework Equations
Sum of Moments = 0
Sum of Forces = 0
The Attempt at a Solution
Moments act around bottom of plate
F*L1=L2*Fa+L3*Fb
Vertical Forces
F=Fa+Fb
Fb=F-Fa
Horizontal Forces
F=0
So vertical forces into moments
F*L1=L2*Fa+L3*(F-Fa)
Fa= F (L1-L3)
-------------
L2 - L3
It doesn't feel right can someone tell me if I've done it right cheers
