Question

a 60 kg girl wearing a high heel shoes balances on a single heel. the heel is circular with radius 1 cm .What will be the pressure exerted by the hell on horizontal floor.

Answer 1

pressur= force/area. force=mg(mass x acceleration due to gravity)
v r ignoring mass of the shoe, because comparitively, much less mass n not added. mass of the girl only included.
area= pie(r^2)
ask if u still hv doubts :)

Answer 2

pressure = stress = normal force / surface area
               = mg / A
           = 60 kg * 9.81m/sec²  /  π 0.01² m²
           = 18.7  * 10⁵ N/m²

This is 18 times the atmospheric pressure.
