The questions
A crate rests on horizontal ground on a square base of side 0.5 m.
The crate exerts a force of 180 N on the ground.
Work out the pressure on the ground.
Give your answer in N/m2.
Show answer
The pressure on a floor is 45 N/m2. The area in contact with the floor is 0.8 m2.
Work out the force.
Show answer
A machine exerts a force of 1200 N on the ground. The pressure is 300 N/m2.
Work out the area of ground in contact with the machine.
Show answer
A force of 150 N acts on a circular base of radius 5 cm.
Work out the pressure in N/cm2. Give your answer correct to 2 decimal places.
Show answer
1 m2 = 10 000 cm2.
- Change a pressure of 2400 N/m2 to N/cm2.
- Change a pressure of 0.5 N/cm2 to N/m2.
Show answer
A solid cube of side 20 cm exerts a force of 160 N on a table. The cube rests on one face.
Work out the pressure on the table in N/m2.
Show answer
A cuboid block has a volume of 0.06 m3 and a height of 0.3 m. It rests on its base on horizontal ground and exerts a force of 900 N.
Work out the pressure on the ground in N/m2.
Show answer
A concrete slab is a cuboid of width 0.8 m and thickness 0.1 m. It lies flat on the ground and exerts a force of 1440 N. The pressure on the ground is 600 N/m2.
Work out the length of the slab.
Show answer
A force of 600 N acts on an area of 0.5 m2. Amy says "If the area is increased by 25%, the pressure will decrease by 25%."
Is Amy correct? You must show your working.
Show answer
A metal box rests on horizontal ground on a rectangular base.
The box exerts a force of 480 N on the ground.
The pressure on the ground is 60 N/m2.
The width of the base is 2.5 m.
Work out the length of the base.
