3) A uniform board 7.5 m long with a mass of 73 kg is attached to a wall with a pivot. A rope with a tension of 850 N that makes an angle of 45° with the horizontal is attached 0.3 m from the left end of the beam and connects the beam to the same wall as the pivot to keep the system balanced. You place an 83 kg wooden crate on the board. How far from the left end can a wooden crate be placed without breaking the rope? (see figure below) 47 Ⓒ = 45°
