An axial thrust of 1.6 kN is applied to the clutch. Given that, the outer contact radius, and the inner contact radius is, carry out the following: (a) Establish how many discs will be engaged during operation. [2 marks] (b) Determine the friction torque required to operate the clutch Assume the clutch operates under uniform pressure. [4 Marks] (c) What is the average pressure needed for effective clutch operation? [3 Marks] (d) Discuss three common problems associated with the disc clutch. What are the solutions to these problems? [3 Marks]
