A woman wearing high-heeled shoes stands on a wooden floor. Her total weight is 480N and acts equally on each foot.
Sometimes all this weight acts on the soles of her shoes. What is the pressure under her soles?
area under sole 40cm squared
are under heel 2cm squared
To find the pressure under the soles of her shoes, we can use the formula:
Pressure = Force / Area
The total weight of the woman is acting equally on each foot, so the force acting on each sole is half of her total weight, which is 480N / 2 = 240N.
Given that the area under each sole is 40 cm², we can convert it to square meters:
Area = 40 cm² = 40 cm² / 10000 = 0.004 m²
Now we can calculate the pressure:
Pressure = 240N / 0.004 m² = 60,000 Pa
Therefore, the pressure under the soles of her shoes is 60,000 Pascal (Pa).
