A 50 kg girl wearing high heel shoes balances on a single heel. The heel is circular with a diameter 1.0 cm. What is the pressure exerted by the heel on the horizontal floor ?
Given, the mass of the girl is 50 kg , the diameter of the heel is 1.0 cm .
The pressure exerted by the heel on the floor is given by the equation,
P = F A = m g π 4 d 2
Substituting the values in the above expression, we get:
P = 50 kg × 9.8 m / s 2 π 4 ( 1.0 × 10 − 2 m ) 2 ≈ 6.2 × 10 6 Pa
Hence, the pressure exerted by the heel on the floor is 6.2 × 10 6 Pa .
Given, the mass of the girl is
The pressure exerted by the heel on the floor is given by the equation,
Substituting the values in the above expression, we get:
Hence, the pressure exerted by the heel on the floor is
