Here's one for all you Mechanical or Structural engineers.
I have 2 different sheets of Aluminum available to me to use as floor pan material. Which one will provide the greater stiffness to chassis twisting ? Assume that the bonding and attachment is the same for both pieces.
Choice #1: Sheet of 6061 T6 material .080" thick
Choice #2: Sheet of 7075 T6 Alclad (for corrosion resistance) .062" thick
Thanks in advance...............Gary
