Knowing the mass and area of the shoe, calculate how much pressure you apply when walking and how much while
Knowing the mass and area of the shoe, calculate how much pressure you apply when walking and how much while standing still. Weight 54 kg. The number of squares – 761 Determine the support area of the boot as follows: Put on a sheet of checkered paper and outline the contour of the part of the sole on which the foot rests. Count the number of full squares that fall inside the contour, and add to it half the number of incomplete squares through which the line passed contour. Multiply the resulting number by the area of one square (the area of the square is 1 / 4cm (squared)) and find the area of the sole.
N squares-761
m = 54kg
We decide:
S = 761 * 1 / 4≈190cm square = 0.019m. 2
S = 0.019m2
P standing still = 54 * 9.8: 0.019 ~ 27853 Pa
P when walking = 27 853 * 2 = 55 706 Pa
Standing still, the pressure is less because the area of support is two legs, and the larger the area of support, the less pressure, when walking we lean on one leg, which means the area of support is less, and if the area of support is less, then the pressure is greater.
