An automotive type clutch, as shown in figure 18.2, has an inside diameter of 130 mm and an outside diameter of 220 mm. The clamping force is provided by 9 springs, each compressed 7 mm to give a force (per spring) of 600 N when the clutch is new. The molded friction material provides an estimated coefficient of friction of 0.6 when in contact with the flywheel and pressure plate. The maximum torque provided by the engine is 260 Nm. a.) Even though the maximum torque produced by the engine is 260 Nm, the clutch is capable of transferring significantly more torque when it is "new". What is the maximum torque the "new" clutch can transfer? b.) What is the "Safety Factor" with respect to slippage for a "new" clutch? c.) Even though the maximum torque produced by the engine is 260 Nm, the clutch is capable of transferring significantly more torque even after initial wear (break in) has occurred. What is the maximum torque the "broken in" clutch can transfer? d.) What is the “Safety Factor" with respect to slippage after initial wear (break in) has occurred?
