Rubber Bands and Paper Clip Hi all. I have a question. How do
you show the difference between stress (pressure) and force? We
were given 2 short elastic bands, 2 long elastic bands, and 2
paper clips. Idea that came up was to tie one elastic band to 1
weight (anything). Suspend it. And measure length of elastic
band. Then take 2 same length elastic bands and tie them both to
wait suspending the same weight with the elastic bands side by
side. Then measure the length of the elastic bands. Obviously,
the parallel suspension will have shorter length. This goes to
show that the two elastic bands have twice as much cross
sectional area if you dice the elastic bands than the experiment
with only 1 elastic band. I understand that pressure is the
amount of force per unit area. However, I don't see how this
connects to showing the difference between stress and force? How
do I show it? If i can't with this experiment. What other
experiment can I do? And the other experiment is to show the
differcence between strain and
