We will be looking at newton's 3 laws around Halloween. For the 2nd, f = m x a, I would like to construct a giant spider web and give some force facts about spider silk and webs. How strong is spider silk? How strong is a spider's web? How much force can silk withstand? How much force can the whole web withstand?If you have any more ideas for the holidays, please send them! Thanks, Joan.

Answer 1:

I have published papers about forces in spider silk and spider webs.

Here is a link to some news article about this work:

spider silk

HHspider silk

Here's a link to a news article about my friend, Prof. Cheryl Hayashi atUC Riverside, and her spider silk research:

spidersilk

That doesn't give you much info about F = m a. We tend to be more interested in Work = Force x Distance.

We measure the forces as we stretch the silk various distances - nanometers with our Molecular Force Probes and millimeters when we hang tiny weights onto lengths of spiderweb.
