The floor on a dance hall can take a pressure of 3.5 MPa before getting damaged. A lady of mass 60kg wears high heeled shoes. What is the smallest area of the sole of a heel she could wear such that it won't permanently damage the floor?
Area = Force/Pressure
The Attempt at a Solution
3.5 MPa = 3500000 Pa
Force (weight) = 60 x 9.8 = 588N
But I don't know where to go from there...I tried just dividing Force by Pressure but got a different answer to that in the book. Thanks in advance to anyone that can help! :-)
