What is the tension in the right cable?

[MadMcB]

Homework Statement

2 cables are used to support a 24kg mass on a 1.6m long, 8kg uniform horizontal beam. The 24kg mass is 0.6m from the right cable. What is the tension in the right cable?

Homework Equations

torque = rFsinx

The Attempt at a Solution

Fy = ma = 24(9.8) = 235.2N
Fx = ?
resultant F - ?[/B]

There is no Fx forces acting if I'm visualizing it correctly.A picture would help.
Take moments about the left end, solve for the one unknown force - the rhs cable tension.

Is the object moving? If so or if not, what does this tell you about the net force.

And are the cables vertical? Where are they attached to the beam? At the ends ?

There is some confused thinking here:

Fy = ma = 24(9.8) = 235.2N

Fy = ma should be $\Sigma F_y = ma_y$, i.e. the net force in the Y direction gives rise to an acceleration in the Y direction.
It is not clear whether you are considering forces on the beam, forces on the mass, or forces on the two as a system. Whichever, 24(9.8) is only one force in the Y direction, not the net force.
I assume the cables are vertical and attached to the ends of the beam. If so, follow billy_joule's advice. You can get the answer without using $\Sigma F_y = ma_y$.
