A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.2 kg and the sign has a mass of m5 = 17.1 kg. The length of the beam is L = 2.51 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The angle the wire makes with the beam is 6 = 33.6. 1) What is the tension in the wire? N 2) What is the net force the hinge exerts on the beam? N 3) The maximum tension the wire can have without breaking is T = 859 N. What is the maximum mass sign that can be hung from the beam? kg 4) What else could be done in order to be able to hold a heavier sign? while still keeping it horizontal, attach the wire to the end of the beam keeping the wire attached at the same location on the beam, make the wire perpendicular to the beam attach the sign on the beam closer to the wall shorten the length of the wire attaching the box to the beam The electric power generated by a single average size nuclear reactor block is typically between 400 and 800 MW. The fission of one 235U nucleus generates 185.0 MeV energy on average. Consider a 540.0 MW reactor for a one year period. The reactor is loaded with Uranium fuel containing 5.00 percent of 235U? Assume that the overall thermodynamic efficiency of converting heat to electric energy at this power plant is 36.0 percent. What is the total amount of electric energy generated by the reactor block in one year? Submit Answer Tries 0/12 What is the total amount of heat produced by the reactor block in one year? Submit Answer Tries 0/12 How many Uranium fissions produced this amount of heat? Submit Answer Tries 0/12 At least how much Uranium fuel needs to be loaded into the reactor for a one year long run? Submit Answer Tries 0/12
