Sand Center
If I meet an iron pipe with sand and finish the crown, which will become stronger?

I built a Trebuchet and a 1 "tube iron is not in itself sufficient to hold 540 pounds, bent after one use. It is 1 "to pass through my lever. I thought to fill with sand, other ideas? Tips and ideas on leveling, or simply can with orange caps as that comes with it or do I make ends stronger. (The weight is everyone in the center of the pipe pulling down)

Talk about a 1 "tube shaft. Fill with sand, or rather concrete, providing a resistance basic compression, increasing the resistance of bending load. (The walls are kept to a load higher quality compression.) If you use sand, it must be carefully packaged and sealed the ends firmly. (plastic lids are not cut.) The "surcharge" imposed if more that the deadweight of its fight against the # 540. It is the energy of the impact of the falling weight through its travel, less any transfers to the device. You may be only a heavy missile actually reduces stress on your hose. (I bet you dry "fired" Is that the first time right? – Is the limit "question of stress). The trebuchet project is designed to teach mechanics is not?
