Consider a beam as shown in the figure that is 2 m long and supported by a rope. It is pressed against the wall. There is no friction between the wall and the beam. If the beam has a mass of 2 kg and a sign with a mass of 10 kg is hung off of the end of the beam, can the system be in static equilibrium? If so, what is the tension in the rope?
