An 8.0m long uniform boom weighing 1200N is anchored to the ground at one end and sticks up at 35 degrees above the horizontal toward the right. It is held in this position by a horizontal cable at ratchet to the top of the beam and pulling left with tension T. If a 600N weight hangs from the top of this boom what is the tension in that cable. I would suggest using the bottom end of the boom as your pivot point for calculating the torques.
