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?
the angle between the top rope and the beam is 30 degrees
