Assume a person's mass is 50 kg and each of her shoes has an area of 195 cm². What is the compressive stress on her feet if her weight is spread out evenly over both soles of her shoes?

Answer :

Final answer:

The compressive stress on the person's feet is 2564.1 Pa.

Explanation:

To calculate the compressive stress on a person's feet, we need to divide the person's weight by the area of both shoe soles. In this case, the person's mass is 50 kg and each shoe sole has an area of 195 cm².

First, we need to convert the area to square meters, which is 0.0195 m².

Then, we divide the weight (50 kg) by the area (0.0195 m²) to find the compressive stress:

Compressive stress = Weight/Area = 50 kg / 0.0195 m² = 2564.1 Pa
