normally, a hypothesis will test or compare something to a control. If you have one bridge, which you have designed and build, here are some examples
Bridge will hold a 65 lb weight suspended from the center for 456 seconds.
now that is really not much to brag about, as if the bridge fails, you have learned nothing. So I would conduct the experiment in stages, noting the weight.
start of with 10 lbs, note results.
then add 10, note results, and so on.
At least you will get to a point of failure and you know the limit, or you will get to 456 lbs and declare success of your hypothesis test, and go celebrate by buying a round of popsicles.
A better hypothesis would be to compare two bridges designed differently. Such as
The span bridge will hold more weight than the XXXX bridge given the same bridge weight.
writing a hypothesis---
how many pounds of weight can be held by a bridge made out of 30 Popsicle sticks.
