Question

A $50	ext{ kg}$ girl wearing high heel shoes balances on a single heel. The heel is circular with a diameter of $1.0	ext{ cm}$. What is the pressure exerted by the heel on the horizontal floor? ($g = 9.8	ext{ m/s}^2$)

Professor PC Thomas Classes · Answer

$P = \frac{F}{A} = \frac{50 	imes 9.8}{\pi (0.5 	imes 10^{-2})^2} = \frac{490}{\pi 	imes 0.25 	imes 10^{-4}} = \frac{490}{0.785 	imes 10^{-4}} \approx 6.24 	imes 10^6	ext{ Pa}$.
