Question

Hi I need help with this question and answering the steps for it 

An 650-N painter stands 2.3 m from the right side of a 9-m-long beam of a scaffold, which is connected to cables at each end. The force exerted by Earth on the uniform beam is 246 N. Determine the forces that the cables exert on each end of the beam. Assume that g=10\frac{\text{N}}{\text{kg}}g=10kgN​

  1. Draw a sketch of the situation, labeling all of the physical quantities given in the problem. Identify your system in the sketch. Make sure all relevant moments in time are shown in your sketch.
  2. Draw an extended-body force diagram showing all of the forces exerted on the bean and the points at which those forces are being exerted.
  3. Solve for force each cable exerts on the beam. Start with general equations and explain what you are doing and why you did what you did.
  4. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.
