From the table the maximum time taken is for Medical exam and treatment for first visit. This can be expanded double so that time will be reduced to 0.25 for Ivisit and 0.125 for II visit. The reception/discharge can be reduced by 25% so that first visit time = 0.30 and second = 0.15

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
