Trebuchet counterweight case studies





 

 

I am researching a counterweight trebuchet. The things works when you put the projectiles in the sling and the weight is on the same arm at the other end. When you let go of the arm the weight carries it down and the arm swings and releases the projectiles. It is like a seesaw when you hold the lighter end. You let it go and the heavy side goes down. I wont to work on this because I think this is easy to accomplish and it puts a lot of force and velocity into the arm when you shoot the projectiles.

 

 

 

 

 

 

Case Study #1 Lindsey and her family

 

 First the group had to overcome what was  getting past the formidable defenses - a 6-foot high wooden fence with reinforced gate. This lead to the 5.85m  high counterweight being installed and the trebuchet including an added 2m of sling. The positives are that it gives us a good example of a counterweight that works, easy design modeling, and gives good perspective on a strong base. Negatives are it is to big for us to build, not enough information on how they built it, and we don't have the time to build it.

Case Study #2 Luc Viatour


 The dimensions are2,469 × 1,944.
The positive are good perspective on the counterweight use, well designed, and good strong foundation. Negatives are to big for us to build, no building instructions, and no feedback on the design.
