Trebuchet

At first building a b tout ensembleista bring together the likes of a fun and easy jump out. However, the mechanics were easily de nonative on paper but difficult to duplicate on the machine. indeed simple figure of speech on paper was misdirect compared to how unfeignedly difficult it was to build. Our trebuchet is composed of ply timberlandwind instrument collectible to its strength. With the chief(prenominal) body of the trebuchet organism 18 inches high, 18 inches walloping and a foot wide. A 2x4 was used to waiting up the axel and thro reference offshoot. The spike was make out of distract dilapidated to the fact that it is wieldable and could easily hold up the fifteen-pound lean marry to the devastation of it. In orderliness for the arm to s vaporize a universal joint from a car drive bang was used. This allowed the least amount of friction possible for the throwing arm, which is both feet abundant releasing point to axel, and 8 inches axel to load . Then a fall away weight was attached to the end of the arm by tire into the weight and wielding it to the throwing arm. It has release mechanism, which was make by a butt, monster wing nuts and an eyehook. The degree of the eyehook can be dip plain by tighten and loosening a wing nut. The greater the degree of the eye hook the longer Finally, project, made out of an old pair of kaki pant and deuce strands about a foot long, was attached to the throwing arm with a hose clamp.         However, this was the non the original design of the trebuchet. At First, the weight was hanging, in theory this would add more(prenominal) pulsing, and recall a straighter path for the weight to follow, eliminating the need for wheels. A screw and a chain link on each place of the weight held up by a threaded celestial bet on through the throwing arm. The throwing arm was about 3 feet long and the emit being about 6 inches. Unfortunately, with the first launching t hings did non go as planed. The lightsome ! weight actually had excessively much freedom taking a guidance momentum and tingle trebuchet violently. To fix the problem cardinal 2X2 wood blocks were added on the front and the back of the trebuchet to give it more support. Again, the wavering weight had too much freedom. It was determined that there were two cistrons impeding the success of the trebuchet. One being the swinging weight, fixable by wielding it on the throwing arm, and two the throwing arm being to long. Since the prognosticate weight was now fixed, wheels would have to be added. Secondly, it was believed that the throwing arm was to long, so a foot was cut off. These change greatly change the action and steadiness of the trebuchet. Next, we had trouble finding the right design for the sling. A couple different types of material were used for the sling, many an(prenominal) of which simply ripped. Also, we tested different styles in attaching the sling. Just two holes displace the center proved to be mo re efficacious than two holes on each side so all quadruplet corners would be pulled evenly.

And old pant material was elect for the sling because the stitching was the right width to hold the string and not rip. Next, a chute was constructed to direct the ball so it would not fall out of the sling. It is constructed out a darn of wood flooring and two pieces of trim nailed together. The chute is a keystone part of the launch stage ensuring that the arugula has a untroubled start. Finally the release point was a unexpressed factor to determine, considering that it would work great one time, then the nigh without changing a variable it would not work. And the weight of the project meant a different angle for the release had to be det! ermined. A heavier projectile tends to pull the loop off the prong earlier than a ignitor projectile does. Golf balls ended up being the more or less successful projectile. In the end our trebuchet shot the golf game ball near thirty-five feet. Unfortunately, the trebuchet was not conformable at all. This whitethorn be due to the trigger of the trebuchet; since it is so coterminous to the release mechanism it maybe touch the release point. another(prenominal) change that could be made would be to extend the primeval axel to have it go all the way through the intravenous feeding 2X4, adding more stability.
