I am trying to make a Catapult/Trebuchet in blender,
how would I combine the weight with the fulcrum on a pivoting cylinder? How
would I make the cylinder that is between two extruded surfaces of a cube
pivotable? How would I make the fulcrum pivot on the cylinder? I am doing
this for a Physics project and my current class where I am learning Blender
doesn’t cover this type of thing. It is do next Monday. Please help!
Hi, it might help if you add a download with what you already have. And some explanation of what you have already tried will also help find out where it went wrong.
That is the thing. I don’t have anything really… And the date it was due was today… 
But I would still love to know how to make this.
Use the rigid body capabilities of 2.66a, and look at “rigid body constraints” - “hinge” in particular.
