Two materials with 10 mm² contact area have been tested to determine how much adhesive wear takes place when they are run together. Table P7-1 shows the test parameters and average depth-of-wear results for 350 tests. Find the average wear coefficient if the Brinell hardness of the softer of the two materials tested is HB 277
