Answer:
30,000N/m²
Explanation:
Given parameters:
Pressure on two legs = 15000N/m²
Total surface area of contact = 0.02m²
Surface area on one leg = [tex]\frac{0.02}{2}[/tex] = 0.01m²
Unknown:
Pressure exerted if she stood on one leg = ?
Solution:
Pressure is the force per unit area on a body.
Pressure = [tex]\frac{force}{area}[/tex]
The force she is exerting is due to the weight her both. Standing on both feet and on a single feet is based on the same source of force;
Force = pressure x area
Force = 15000 x 0.02 = 300N
So;
Pressure from one leg = [tex]\frac{300}{0.01}[/tex] = 30,000N/m²
