Floating Arm Trebuchet Case Studies



Summary
Unlike a traditional counterweight trebuchet, which uses axle fixed to the frame, axle of a floating arm trebuchet is not fixed to the frame. A floating arm trebuchet's arm is mounted on wheels that roll on a track parallel to the ground, with a counterweight that falls vertically, allowing for greater efficiency by increasing the proportion of energy transferred to the projectile. I would like to work on the floating arm trebuchet because the design of it is more interesting and efficient.



Case Study #1
Rating: 7/10

Positives
  • Visual representation of how the trebuchet works
  • Specifications of the trebuchet
  • Explains the advantages of the floating arm trebuchet
Negatives
  • Does not explains specific materials used in the trebuchet
  • Does not provide measurements/plans/blue prints

Case Study #2
Rating: 9/10

Positives
  • Great visual representation
  • Provides pictures of each parts of the trebuchet
  • Provides pictures of the process of making the trebuchet
  • Provides all of the dimensions and materials used in the trebuchet
  • Provides 3D model of the trebuchet

Negatives
  • There is not a visual representation of how the trebuchet works, such as a video or pictures
  • The efficiency of the trebuchet (weight of the counterweight, weight of the projectile, how far the projectile was launched) is not included
