While making our cardboard trebuchet we had to make sure we had a secure base that could hold everything together and be able to withstand the mass of the weights. We also had to make sure that our swinging arm would release the marble at a 45 degree angle. If anything is launched at 45 degrees it will most likely go the farthest because of its horizontal velocity being somewhat great and its vertical velocity being somewhere between high and low.
When we were trying to make our marble go the farthest we had to add more weight. In order for our trebuchet to launch our marble as far as it could we adjusted our angle and used 43 washers as weights. This allowed our marble to be launched approximately 5 meters.
When we were doing the accuracy test we used 30 washers. Our marble landed in different spots close to where it was supposed to land. This test proved that our cardboard trebuchet was not very accurate.
Some environmental factors that could affect a cardboard trebuchet are;
- The glue could wear away resulting in the whole trebuchet falling apart
- If the trebuchet gets wet it will not be able to perform at its best because the cardboard will be weaker
