A rod made of 60-40 brass is sliding over unlubricated hardened tool steel with a load of 320 N. The hardness of brass is 520 MN/m2. The wear co-efficient is 10-3. Find: a. The distance traveled to produce a wear of volume of 0.01 mm3 by the adhesive wear of the brass rod. b. The distance traveled, if additional load of 0.0069 kN is applied and a wear volume 7 mm3
