The pressure of a sheet of metal is 7N/cm2 7N Force of 28N on an area of .cm2 1cm1cm .. N exerted on an area of 5cm2 .N exerted on an area of 8cm2 Force of 63N on an area of .cm2
Find the pressure exerted by a force of 8000 Newtons on an area of 25m2. Give your answer in N/m2 A crate exerts a force of 120 newtons on a table. The pressure on the table is 15 N/m2. Calculate the area of the crate that is in contact with the table. A box is placed on the floor. The area of the box in contact with the floor is 2.4m2 Pressure exerted on the floor 16 N/m2. Work out the force exerted by the box on the floor.
