Problem 13.7: Analyze a system of two rods, each attached to hinges

Please wait for the animation to completely load.

Two uniform rods are hinged to a wall and screwed to each other as shown in the animation. The mass of the blue rod is 2.0 kg and the mass of the black rod is 1.5 kg (position is given in meters). Restart.

  1. What are the magnitude and direction of the force of the top hinge on the black rod?
  2. What are the magnitude and direction of the force of the bottom hinge on the blue rod?
  3. What are the magnitude and direction of the force on each rod due to the screw attaching the rods? Your answer should include two forces, the force of the screw on the blue rod and the force of the screw on the black rod.
