3. A 137 kg uniform horizontal beam is attached to a vertical wall and is supported by a wire, as shown in figure 2. The beam is 3.0 m long, and a 756 kg crate hangs from the end. Find the tension in the wire and the force of the wall against the beam. 4. If the wire in problem no.3 is steel and 1.75 m long before the load is attached to the beam, how much does the wire stretch under the load? What maximum load could the apparatus in problem no.4 handle. (Ys = 20 10 Pa, U.S. = 0.05 x 1010 Pa, taking the U.S. to be the breaking point.)
