Lateral strength? Answered
I will be building some kayak carts out of PVC, and I was wondering about side stress, using schedule 40, versus schedule 80? I noticed you mentioned that 80 is thicker than 40, and will handle higher pressure / higher temperature. Will this equate to higher sideways stress?
My cart will start as a basic "H" shape, with additional cross bars at the bottom, (where the axle will go through), and up the body, for bracing, with the top of the "H" left open. The top will get slipped into the scupper holes, and allows the kayak to be rolled along without the need for strapping the kayak to the cart. The last one I built worked well, but when I pulled my boat over a curb, the lateral stress caused the PVC to break. That cart was made out of schedule 40, and I was wondering if building it out of 80 would help?
On a related note, it there any material I can pour into the cart, to increase strength? My initial thought was to fill it with epoxy, though that would be expensive.
Thank you for this great class.
