Calculate the pressure developed by a force of 50 N acting on an area of 10 m2.
Force F = 50 N
Area A = 10 m2
Pressure is defined as the force per unit area. Pressure = ForceArea.
= 5010 = 5 Pa
A body of dimensions 2m × 3m × 4m is acted upon by a force of 50N on the top surface (2m × 3m). Calculate the pressure due to the force on that surface.
(a) Define pressure. (b) What is the relation between pressure, force and area ? (c) Calculate the pressure when a force of 200 N is exerted on an area of :
(i) 10m2 (ii) 5m2
