Click For Summary
The discussion revolves around comparing the pressure exerted on a foot by two different types of footwear: sneakers worn by a male basketball player and heels worn by a woman. It is established that pressure is calculated using the formula P = F/A, where pressure increases as the area decreases. The conclusion drawn is that the woman in heels exerts more pressure due to the smaller area of her shoe compared to sneakers. Participants also engage in light-hearted banter about the scenario, but the focus remains on the mathematical proof of pressure differences. The conversation emphasizes the importance of understanding the relationship between force, area, and pressure in practical situations.

Homework Statement


Suppose you are standing directly behind someone who steps back and accidentally stomps on your foot with the heel of one shoe. Would you be better of if that person were:


Homework Equations


a.) a male basketball player wearing sneakers or
b.) a woman wearing heel shoes

The Attempt at a Solution



suppose they exert the same force, but of course they have different pressure and area, and I already conclude that the woman wearing heel shoes will exert more pressure since less area=more pressure. but how can i prove it mathematically?

THANKS!

You just did.

P = F/A

If: Aheel < Asneakers

Then: F/Aheel > F/Asneakers
 
On the whole, I think I'd be better off it were a hot woman in heels and she felt so sorry that she had to make it up to me in some way. :biggrin:

Just thinking laterally... :wink:

thanks. but how??
could you elaborate more?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
