Example 17.22. Find out the number of turns a hauling rope must be wound round a rotating capstan in order to haul a load of 3 MN up to a gradient of 1 in 30. Presume the following data: Resistance due to rolling = 0.00375 per newton load Friction coefficient between the rope and drum = 0.35 Pull on the free end of the rope = 250 N
