 * Physics 30 Trebuchet project**

The trebuchet was made for battles. The were suppose to either to smash masonry wall or to throw projectiles over them. Nowadays we don't make them to hurt people, we make them for fun. Especially for this physics class. We each had to make a trebuchet, which tested our skills on making them work.
 * Introduction**


 * List of Materials**
 * Hemlock wood
 * String
 * Nails
 * Wood glue
 * Plastic
 * Bolt


 * Procedure**
 * 1) decided what the measurements were going to be, then cut them. the base was 7 cm, the sides were 6 cm, and the supporting beans were 42 cm long.


 * 2) Then glued the pieces together, and stapled them. Which made the main structure of it.
 * 3) Also figured out how long the are would be. Later the arm was switched for a smaller one.




 * 4) Next was to figure out how much the weight should weigh. First there was water in the bottle then switched to pennies because it needed more weight.




 * Discussion**

I made some few adjustments to the trebuchet. The weight was switched from water to pennies, because there wasn't enough weight to throw it very well. Also the arm length was changed too. It needed to be shorter, so it was cut and could throw the ball better and further. After that everything started working except the sling. I tried many slings but non of them were workings, so i attached a string to the end of the sling and tied it to the base. When the trebuchet would shoot the ball the string would let the sling release the ball so it would actually come out.
