Suppose you're building a contraption which contains a solid rod of length L = 15.6 m and mass 5.2 kg. This rod has its lower end barely above the ground at an angle of 25.4 degrees with respect to the horizontal, and is ultimately held up by a rope connected at a distance L/4 from the top of the rod making an angle of 25.1 degrees with respect to the rod. The top of the rod may rotate as it is held in place by a bolt connected to a wall. Calculate the tension in the rope which keeps the rod from touching the ground.

Answer rating: 100% (QA)

To calculate the tension in the rope we first need to determine the forces acting on the rod and the... View the full answer
