Heels VS Flat shoes
have you ever see the woman using High heels or Flat shoes? what the different from the both?
let's see the pictutes
woman using High heels
woman using flat shoes
from the picture, can you see the different between two shoes? and can you tell me why high heels when walking on the ground will make a hole? anybody knows?
well, the physics consept about the heels and flat shoes is "PRESSURE". there are three kind of pressure:
1. Pressure in Solid
2. Pressure in Liquid
3. Pressure in Gas
but, now I'll tell about Pressure in Solid. as we know, Pressure is the force acting on the object divided by the surface area of the field in which that style works. Mathematically it can be written:
well, from that formula we can calculating something. for example:
if there are 2 kind of shoes, the first shoes have area 10 m^2 and the flat shoes have 30 m^2 and have the same force is 100 N. so which one have the big pressure?
Solution:
F= 100 N
A1= 10 m^2
A2= 30 m^2
P=100/10 = 10 pa
p=100/30 = 3.33 pa
so, the big pressure is high heels. why high heels? because it has The small wide and have big force too. that;s why, when a woman walking in the ground using high heels, the land whereon by women will holey. and when women using flat shoes walking in the park. the land whereon she no holes.
so can you take a conclusion from this matery?
conclusions about the pressure on the solids as follows: Pressure is proportional with force and inversely with Area

oke diska, is the mass of an object can influence the value of pressure?
BalasHapuswhat is the application of solid pressure in daily life?
BalasHapusso what better for health???? the high or the flat?
BalasHapusand then if an object have force very small and very large cross-sectional area how with the preassere?
