This member did have angled bracing to stop bowing and this brace did not snap it was only the glue joins in this brace that failed.

Popsicle Bridge #1
Popsicle Bridge #2
Popsicle Bridge #3
Popsicle bridges provide a unique challenge because of the limited length of the popsicle sticks. This hurts the inherent strength especially in tension. Ideally, a member of the bridge in tension would be one [...]
