7. Summary Acetal prongs break at 30% of their original length L=.5 in
ΔL=.3(.5 in)=.15 in
E=3.63e5 psi
A=1/64 in^2
Max Capacity per prong: F=((ΔL)EA)/L= 1702 lbs
This is the amount of force to stretch a prong to a breaking point perpendicular to the length
Taking 171 average weight grocery bags to break our design, our invention won’t be breaking any time soon!
