Weight held by a beam and cable

[EchoTheCat]

I've got a problem where a weight is being held to the side of a building using a beam and a cable. The weight is 336 pounds and the angle between the cable and the beam is 49 degrees. I need to calculate the tension of the cable and the force of the beam. I calculated the force of gravity as being 336*9.8 = 3292.8 lbf. If the tension in the cable is T, then sin 49 degrees = 3292.8 / T. I solved for T to be 4363.0027845 lbf. I calculated the force of the beam to be 3292.8/tan 49 degrees = 2862.4 lbf, but that's not the correct answer. I don't know what I've done wrong?

The objects weight is already given in force units, not mass units. Why are you multiplying it by g? The weight of any object is always in force units in USA or SI systems of measure.

You're right. Thank you!
