Here's my problem: The heels on a pair of women's shoes haveradii of .50cm at the bottom. If 30% of the wieght of a womanweighing 480N is supported by each heel, find the stress on eachheel? I thought you would use stress= elastic modulus x strainequation but apparently im wrong. I'm not sure where to go fromhere.

Explanation / Answer
Radius of heels of women : 0.50 cm = 0.005 m Area of heel = R2 = 3.14 * (0.005)2 = 7.85 x 10-5 m2 Weigth of women = 480 N 30% of the wieght of a woman is : (30/100) * 480 = 144N Force supported on each heel is 144N Now stress is : F / A = F / R2 = 144 / 7.85 x 10-5 = 1.8 x 106 Pa Hope this helps u! = 1.8 x 106 Pa Hope this helps u!
