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.

## Homework Equations

My force diagram.

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.
