A uniform beam used to unload beer barrels from wagons at a tavern in a town’s historic district has a mass of 20 kg and is 3.0 m long. It is supported horizontally by a small loose bolt attached to the wall at one end and by a wire at the other end, as shown in the figure. What is the tension in the wire?

  • A) 120 N
  • B) 200 N
  • C) 230 N
  • D) 300 N
  • E) 460 N

♦ Relevant knowledge
Find the tension at both end of the rope. The tension of the rope results from the both ends pulling. Repetition using the equation “force = mass + acceleration. Assuming that the rope is stretched to a very tight stretch every change in speed or weight of the object results in changes in the tension of the rope. Be aware of the force-induced acceleration even when the system is in rest every part of the system will be subject to the force. The formula for string tension T = (m x g) + (m x a) In that formula “g” represents the speed of acceleration caused by gravity of the objects within the system, and “a” refers to the particular acceleration of the body.
