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.

The project requirements for the sumobot was to build a running car with the parts that were given to us by Mr. Atkins in the box of stuff. We built up the project with motors and batteries and got the control box to run the course. We ran the course in two minutes and twenty four seconds and that was 60% of our grade. We made our design of McDonalds because we had most of our colors red and Steve came up with the idea.

My group came in third place out of five. RDJ came in first followed by John Deer then Ronald (my group) then ASAP Fury and last but not least, Bloody Mary.

We would make our wheels perfectly straight and not be able to move at all. The front wheel would have more traction so it could turn. That was the problem with my groups project. We had speed but not torque on our wheels. Plus our gear drive project was worth it we just need to fix the torque and have a better distribution of weight on our project.

 My group was Troy Joey and I and we made a yo-yo with a optical illusion attached to it. Our illusion made the colors blue and orange and these are complementary colors. We first made two circles with the drill press and we made them the same size. Then we took a rod and glued the two circles together with the rod attached to it. Then we had to attach a rob to the yo-yo so we can make it spin to make the illusion. Our group performed a good yo-yo and we achieved our task.

Our group did create a optical illusion and we did succeed in using the color theory in it. The colors we made in the illusion were blue and orange. Many groups also achieved their goals and overall this project was a success for our class. A lot of interesting and creative designs were made.

My group could have improved our project if we had more time. We wanted to make a smaller and less weighted circles for the yo-yo. Our string was a big struggle and if affected the outcome of our project. We needed to get a smaller string and it would have created more spin for our illusion.

This project we had to work in groups. My group was Troy, Joey, and me. We had to use fasteners to hold blocks of would together. A fastener is something that hold two or more objects together. My groups fastener was magnets. We had to come up with designs to use the magnets. We came up with a person.

 

My group did achieve success in this project. The goal was to use our fastener and keep the blocks together. We had our person stand up and the wood did stay together with the magnets holding in place. We had so difficulties in our project such as we had to cut down the wait to make it not as top heavy. Also it was hard to keep the person stand up do to the legs were not as stable. But overall we got the person to stand and used the magnets correctly.

 

The group that was successful was Matt Munez's group. They used wooden pegs to hold up blocks of would and built of a pyramid. Factors that led up to their success was that the pegs were more stable then the other fasteners and the bottom of the pyramid was easy to make. We can use this project in future ones because we will need to keep more than one object together and we will use other fasteners to make it stable. We need to learn from all projects because it helps us better in each project we do
