I guys I need some help trying to find something out.
We were disscussing some aircraft structures before my sheetmetal class a couple of days ago and none of of could remember which one was a Pratt Truss and which one was a Warren truss.
One uses wire on the diagonal to stiffen the structure and the other uses tube metal. The question is which one is which. I know that the old Eaglerock biplanes used a Pratt truss for it's fuselauge but I can't remember it was wire braced or not.
Any help is much appreciated.
