I admit I didn't do so well at high school physics--and that class was a long time ago. I'm not sure this subject was covered, though.
When I use a floor pump, it seems that I cannot inflate my tires to more pounds per square inch than pounds of my body weight. Even if I put all my weight on my hands and take my feet off the ground, I still cannot put enough air in the tires for a TT (and barely enough for commuting). Does this reflect how much I weigh, or how little upper-body strength I have?
I know all you 160-pound guys have never encountered this problem, so I'm sure you'll have lots of speculation to offer. Just don't blame me when I can't be a self-sufficient cyclist.
