Thrust

The force applied on a surface in a
direction perpendicular to the
surface
Unit
= Newton (N)
Pressure


The effect of thrust per unit area is
called pressure.
Pressure =thrust/area

Unit – Pascal (Pa)

Pressure depends on two
factors
1.force(thrust)-more force more
pressure
 2.area -more area less pressure

“The same force produces less
pressure if it acts on a large
area but can produce less
pressure if acts on a small
area.”

Transcripts - pressure & application

  • 1. Thrust  The force applied on a surface in a direction perpendicular to the surface Unit = Newton (N)
  • 2. Pressure   The effect of thrust per unit area is called pressure. Pressure =thrust/area  Unit – Pascal (Pa)  1 Pa = 1 N / 1m2
  • 3. Pressure depends on two factors 1.force(thrust)-more force more pressure  2.area -more area less pressure 
  • 4. “The same force produces less pressure if it acts on a large area but can produce less pressure if acts on a small area.”
  • 5. Every day observation  1.School bags have wide straps so the weight of bag may fall over a large area of the shoulder of the student producing less pressure on shoulder.
  • 6. Sharp knife cuts better than a blunt knife so the force of our hand falls over a very small area of object produces large pressure.
  • 7. The tractor have broad tyres so there is less pressure on ground and do not sinking to comparatively soft field.
  • 8. It is easier to walk on soft sand if we have flat shoes rather than shoes with sharp heels.
  • 9. The foundations of buildings and dams are laid on a larger area to produce less pressure
  • 10. >The wooden or concrete sleepers are kept below the railway line. >A wide belt is provided over the wheels of an army tank.
