Glenforest Secondary School To- Mr. Yeo & Mr. Snider By - Feroze Noorudin June 17th, 2011 TIJ1D0 For oer a thousand eld, aggregated have used respective(a) techniques to move an object by dint of and through the air. Whether for the purpose of combat or simple transportation, the baron to actuate something over presbyopic distance has been vital to the appendage and growing of civilization. During the Middle Ages, forwards the cannons were invented, the most common and fashionable mood to shoot a foxile was the sling. However, over the line of work of the years arbalests have disoriented their popularity. We decided to bring it post! The over each(prenominal) goal for this project is to build a trebuchet in club to fork out our very own Gryphy, the work mascot. Strengths - build the trebuchet take some precise calculations and drawings. We hypothecate a rough survey of what we wanted to accomplish. It was drawn with holding in mind all the supports, pivot points, angles, and joints required for a permanent trebuchet. We cut all our pieces prior to building so we could manikin our trebuchet. This allowed us to fasten certain that all of our proposed cuts, angles, and joints would kick the bucket to travelher. By doing this, we were able to commute the dimensions of certain parts of the trebuchet that were cause problems.

For example, at firstborn we had decided to have a much wider base in order to prevent the trebuchet from tipping over onto its side collectible to the forces exerted by the throwing arm. However, we later completed that the axle forthcoming to us was alike fragile. We knew it wasnt thick lavish to care the weight oddly if it was spread over that tenacious distance. We brief our base by almost a fractional so that the axle was much shorter. This appearance the exerted pressure wasnt only when on the axle but was alike on the vertical supports. Also, the emphasis wouldnt be as much. As I tactual sensation at our trebuchet I can say that this is mavin of its strengths as this prevents any remediation from occurring.
