Homework Statement


A weight of 200 pounds is supported by a cable system as shown. Determine all cable forces and the force in the vertical boom BC.


Homework Equations





The Attempt at a Solution



i separated the x compontents and y components:
x:CAcos60-CDcos36.86989765+DEcos15=0
y: CAsin60-CDsin36.86989765+DEsin15-200+CB=0

but this looks like i have too many unknowns????

Hi Puchinita5! :wink:

That's because you've lumped everything together. :rolleyes:

Do equations for the three forces on D, and then equations for the forces on BC. :smile:

(btw, the question doesn't say that the force on BC is vertical)
