Question

define pressure,thrust and also find pressure if thrust is 40and contact area is 68...​

Answer 1

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed

Thrust is the force which moves an aircraft through the air. ... Since thrust is a force, it is a vector quantity having both a magnitude and a direction. The engine does work on the gas and accelerates the gas to the rear of the engine; the thrust is generated in the opposite direction from the accelerated gas.
