Question

Please Explain the full concept of Thrust and Pressure Breifly

Answer 1

Thrust and Pressure. Thrust : Force exerted by an object perpendicular to the surface is called thrust. ... Since, pressure is indirectly proportional to the surface area of the object, thus, pressure increases with decrease in surface area and decreases with increase in surface area.

hope me well

$\boxed{Thrust : }$ Thrust is the total force acting perpendicular on a surface.

Let us consider forces acting on a body in a particular direction in the following
examples ::

(1) $We\:want\:to\:fix\:a\:poster\:on\:a\\Noticeboard\:with\:the\:help\:of\:drawing\\pins.$

When we press a drawing pin, we apply force on the surface area of its head. This force is directed perpendicular to the surface of the board.

(2) $We\:want\:to\:inflate\:a\:tube\:of\:a\\bicycle\:with\:the\:help\:of\:bicycle\\pump.$

We pull out and then push in the handle of the bicycle pump.We apply a force on the surface area of its piston. This force is directed perpendicular to the surface area of the piston.

S.I. unit of Thrust =》 Since chest is of words, its SI unit is same as that of force i.e., (Newton) N.

$\boxed{Pressure :}$ Pressure is defined as the force acting perpendicular on unit area of the surface.

OR

The trust per unit area is called pressure.

Let us see, on what factors the pressure depends?

(1) $Take\:a\:pin\:having\:a\:pointed\:end\\and\:a\:nail\:having\:blunt\:end.$

Press them against a cardboard applying the same force. We find that the pin penetrates deep into the cardboard than the nail. In this case we found that it all depends upon Area .
