Ideas

our first lesson today we got to look at the different materials to build our trebuchet and i am really considering picking the thicker pine to use to actually construct our trebuchet but i am going to do some more research on the materials so i can get the best possible outcome for my trebuchet. i have looked up plans to make the trebuchet and found some ideas that would work this is one of them that i really think could work, i really want to try do the sling as research says that it will make the object go further. 

Research:  - 

The Treb frame should be on wheels if the ground is hard and flat - This allows a slight movement that adds momentum to the throw and prevents the frame shaking itself to bits.

 the weight should be in the form of a swinging box so that as the arm goes over the weight maintains the perfect relationship imparting the maximum momentum to the arm

 The sling is long enough to allow the stone to lie on the platform of the treb as the arm swings it up at the top of the swing the stone will come free and pass between the ropes of the sling. This is an improvement on the fixed cup at the end of the arm because it effectively lengthens the treb arm imparting more momentum.
