Coolest Popsicle Bridge

December 3rd, 2005

This bridge was built by Michael in Quebec.

I have a bridge I built for a physics for engineers class I’m taking in cegep (QUEBEC). My partner and I didn’t have much confidence in it, but it blew the competition away! The design was a fairly straightforward arch as you can see. We primarily focused on keeping the weight of the bridge down. The bridge weighed in at 211 grams.

The efficiency rating worked as follows:
Weight supported by the bridge divided by the weight of the bridge squared.

This was our score. 173 KG./ (.211)squared. Our score was 3886, second place was 2100 and the rest of the competition was well below 2000. Our bridge held 381 pounds! And the lab class which we tested them in ran out of weight for us to load it with, so we couldn’t break the bridge! our teacher is building a hydraulic system to crush it next week!

Michael.

    I definitely agree.

    I am doing a science fair project on bridge design. I think it is amazing that your bridge held 381 pounds. I also want to thank you because you have given me some really great ideas!

    Mark, as I didn’t build this particular bridge I don’t know how many sticks were used. But I bet around 150-175 because of the weight.
