The stress caused by a 70 kg woman in heeled shoes (assume a 6.0- mm -diameter heel) standing on one heel is 0.02638699 N/m.
Stress is a term used to define the strength of the forces that lead to deformation. The general definition of stress is force per unit area. Tensile stress is what we refer to when forces draw on an object and induce its elongation, similar to how an elastic band stretches.
Given that mass, m = 70 kg
diameter = 6.0 mm = 0.6 cm
then, radius,
r = 0.35 cm
= 0.0035 m
A = areas of cross-section
[tex]\pi r^2 \; and\;\;stress = \dfrac{mg}{a}[/tex]
Putting the values in the formula
[tex]stress = \dfrac{(70) (9.8) }{\pi (0.0035)^2} = 0.02638699 \; N/m^2[/tex]
Therefore, the stress caused by the woman is 0.02638699 N/m2.
