In a pin-on-disk wear test, a bronze pin of radius 10mm is placed with its flat face resting on a steel plate under a normal load of 100 N and at a distance of 200 mm from the center of the steel plate which rotates about its axis at 5Hz for 20h. At the end of the test, the specimens are separated and weighed and it is found that the mass losses of the bronze and steel are 250mg and 10mg respectively. Calculate the wear coefficients for bronze and steel if hardness and density of steel and bronze are 2.4 GPa, 0.8 GPa, 7.8Mg/m3 and 8.4Mg/m3 respectively.
