When it comes to measuring force, I suspect you're stuck in "industrial
territory".  Pressure, temperature, and acceleration can be measured
with sensors that can be had at reasonable prices (for the
experimenter/hobbyist, that is) but force is something I've never seen
done in a cheap, easy-to-use package.  Entran has load cells and strain
gages, but these cost US$350 and up.  Honeywell has some solid-state
force sensors (http://content.honeywell.com/sensing/prodinfo/force/) but
I don't know the price or who distributes them.

You can Google for a bunch more, but I don't see anything affordable
unless you've got big bucks.
