Reconsider Problem 9.19, but estimate the volume of metal that will wear away for each of the steel mating surfaces, both of 300 Bhn. All other conditions are the same as in Problem 9.19.

Problem 9.19

A latching mechanism has steel mating surfaces of 100 and 300 Bhn rubbing back and forth over a distance of 30 mm each time the latch is operated. Lubrication is questionable (the surfaces are supposed to get a drop of oil every few months). The latch is operated an average of 30 times per day, every day (see Figure P9.19). Estimate the volume of metal that will wear away from the softer steel member during one year of use if the compressive load between the surfaces is 100 N.
