What is Bearing Pressure

Mar 25 2013 0183 32 = 1kN / 1m 2 = 1 kN/m 2 If this load were increased to say 5000 kg 5T then the pressure applied = 50 / 1 = 50 kN/m 2 If the 50 kN were applied over an area 2m x 2m 4 sq m then the bearing pressure becomes = 50 / 4 = 125 kN/m 2 The important point is whether the load can actually be evenly spread which is a function of the material doing the spreading and whether the ground can take the...
