Examples of Pressure

Examples of Pressure:

Some daily life applications of pressure:

  • The handles of bags, suitcases, etc. are made broad, so that less pressure is exerted on the hand.
  • Buildings are provided with broad foundations, so that the pressure exerted on the ground becomes less.
  • Railway tracks are laid  on cement or iron sleepers. so that the pressure exerted by train could spread over the larger area and thus pressure decreases.
  • Pins, needles and nails are provided with sharp pointed ends to reduce the area and hence to increase the pressure.
  • Cutting tools have sharp edges to reduce the area, so that with lesser force, more pressure could exerted.
  • Pressure on ground is more when a man is walking than when he is standing because in case of walking, the effective area is less.
  • Depression is much more when a man stands on the cushion than when he lies down on it because in standing case, area is lesser than in case of lying.
  • The tractors have tyres, to creates less pressure on the gorund, so that tyres do not sink into comparatively soft ground in the field.
