Apply Load and Test Fasteners

What happens here

The person repeatedly hangs from the edge of the cantilevered OSB platform, applying their full body weight as a load to the fasteners. During this process, the smooth shank nail visibly fails first, pulling out of the OSB. Subsequently, the ring shank nail also fails. The screw, however, maintains its grip in the OSB throughout the test, demonstrating superior holding power under the applied stress.

Goal: Determine which fasteners hold under load
