How Can I Load Balance Two Wireless Routers?

Please help me:Physics problem?

• I have to answer these questions to be able to pass in my physics class. I don't know how to solve this problems. Please help me. I will give 10 points.Its okay if you cannot answer all. Thank you very much! God Bless. I will not sleep just to keep on trying and waiting for your responses. 1. A meter stick is suspended at its center and has a mass of 1 kg. A 3 kg mass is suspended from its left end and a 4 kg mass is suspended 20 cm from its right end. How far from the center is the 3 kg mass if the center stick is in the equilibrium? 2. A 5.8 kg ladder, 1.8 meter long rests on 2 supports. Support A is 0.60 meter from one end, and B is 0.15 meter from the other end. What force does each support exert on the ladder? 3. A 120 Newton child and 200 Newton girl sit at the opposite ends of 4 meter uniform bean pivoted at its center. Where should a 140 N load be placed to balance the beam? 4. If the torque of 0.06 Newton meter is needed to open a pop can and an average person can exert a force of 4 Newton. How long should the handle be made? 5. Two weights, 60.0 N and 50.0 N rest at opposite ends of a horizontal beam. Neglecting the the mass of the beam. Where should the fulcrum be placed to balance it. 6. Two forces, 35.0 N and 25.0 N rest at the opposite ends of a horizontal beam. Where should the fulcrum be placed to balance it? 7. Two forces supports the end of a 5 kg wooden board that is 2 m long. A 2 kg box sits on the board, 0.5 m from one end. Find the magnitude of supporting forces. 8. What torque is needed to keep a 35 cm wheel turning if a force of 120 Newton acts on it?

• Answer:

  you need to review your lever equations. its been two years since i took analytical physics and i dont remember them but there fairly simple. for each problem figure out the force on each side of your fulcrum necessary toeither equal both sides out or for the double ladder one figure out how much downforce is being generated by the things at the end and that is how much the ladders are lifting. dont forget to include the weight of the ladder
