    'Here was my entry. It held 14.6 lbs. I focused on arches at the crucial stress points but didn't consider the side-to-side stress, which seemed to be a week point for many entries.

    Here is my bridge.
    It held 11.2 lbs before breaking at its weak point on the top part of the biggest triangle opening. I knew after seeing it start to bow that it was gonna break there.
