Pressure
- 2. When else involves changes in pressure?
- 4. When is reduced pressure needed?
- 7. How important are feet?
- 8. 6 800 kg Surface area = 15 cm 2 … And that is why Elephingo or Flamphants don’t exist! Pressure = Force / Area = 68 000 / 0.0015 = 45 333 333 N/m 2 = 0.0015 m 2
- 14. Pressure remains the same… Pressure Area = - Force
Notes de l'éditeur
- Low pressure – air rushes inwards to fill up the less dense volume (rotates anticlockwise in the Northern hemisphere) High pressure – air rushes upwards to escape the denser volume (rotates clockwise in the n.h.)
- Spanish gp winner Mark Webber of Red Bull racing – his car like all racing cars deals with changes in pressure due to the movement of air under and over the structure. 747 aircraft designed to transport heavy loads in total of it’s own mass 81,600 kg a speed of Mach 0.75 500 mph/805 km/h. The basics of flight is due to pressure.
- It doesn’t take any magical or spiritual intervention to lie on a bed of nails – it just takes an understanding of Physics and pressure! Shoe design, not only for comfort but to reduce pressure and
- Why can they not be squished any further? The molecules are too closely packed and have a charge between them that forces them apart.
