Relative DensityThe relative density r of a material is the ratio ofits density to the density of water (1000 kg/m 3 ).xr31000 kg/mExamples:Steel (7800 kg/m 3 ) r r= 7.80Brass (8700 kg/m 3 ) r r= 8.70Wood (500 kg/m 3 ) r r= 0.500
PressurePressure is the ratio of a force F to the area Aover which it is applied:ForcePressure ;AreaPFAA = 2 cm 21.5 kgPFA2(1.5 kg)(9.8 m/s )2 x 10 m-4 2P = 73,500 N/m 2
