a) A 10.0 kg crate is resting on a 6.0-meter long horizontal beam with a mass of 5.0 kg and held in place by a wire at a 37-degree angle with respect to the board. Unfortunately, the pivot point is relatively weak, and if the vertical force exceeds 5.0 N, the pivot will break and the board will fall. How close can the crate be moved toward the wall before this happens? What would be the tension in the wire right before this happens?
