Two uniform beams, each of mass M and length L, are connected by a hinge at the top and by a chain of negligible mass attached between their centers. The system will stand upright on a frictionless surface as shown in the figure. Determine (a) the tension in the chain, (b) the force on the hinge by each plank, (c) the force of the ground on each plank, as a function of the length of the chain, l.

Sum of F = 0
Sum of Torque = 0

Torque = (-T sinθ L ) + (-W cos θ L) + (Fx sin θ L) = 0

FxsinθL - WsinθL / sin θL = Tension is this right?

if this is right I will attempt part b.

FxsinθL - WcosθL / sin θL = Tension

edit: FxsinθL - WsinθL / sin θL = Tension

then it will simplfy as ,

T = Fx-W = Tension... now it doesn't even seem right
