Stressed skin materials question
I know this has nothing to do with LSX engines, but you guys are some of the sharpest out there.
These questions pertain to building a stressed skin lightweight chassis for a C5 powertrain (shortened torque tube) and suspension. The center tub would essentially be a twin beam with center backbone, with conventional front and rear stubs to hold the engine/suspension in the front, and transaxle/suspension in the rear. The aluminum skin would be bonded and riveted to the steel structure.
Question:
For the side "tubes" and center backbone, I would be using 1x1x1/8" angle steel to form the box, with 3/4"X3/4"X1/8" stringers periodically to support the skin and keep it from buckling be stonger than the same arrangement with 1x1x.063 square tubing and 3/4"X3/4"X.063 stringers?
If what I am asking is not clear, picture a 5 foot long cardboard box, that is 1 foot high and 5" wide. All of the inside corners would have either the 1" angle or square stock, and every 18" the 3/4" stock would follow the shape of the box.
