A 2-cm square cross-section steel part having a Brinell hardness of 100 and a length of 4 cm is to be ground by adhesive wear using a tool of electroplated chromium with a square head of 2 mm x 2 mm. If the normal force applied is 20 kN and the depth to be removed from the surface is 2 mm, determine the number of passes needed (parallel to the length direction) for good lubrication. Select one: O a. N = 4905 O b. N = 9810 O C.N = 6540 O d. N = 3924
