Factory Five Racing 1933 Ford - The Cobra In Henry's Clothes
|
The '33's chassis is more than just a frame; it's basically a truss as long, wide, and high as the car. Note how the tubes meet headlong at junctions. It's because a tube is considerably stronger in tension or compression than it is in shear. Also note how each tube meets more than one other. Arranging them that way causes force applied to any single tube to dissipate among many others. The design has an incredible amount of structural integrity, and while it looks massive, it is very light on account of relatively thin tubing walls. View Related Article
