2. One of the factors that affect economic decisions is scarcity. What happens when products and resources become less available? How does this affect the incentives
and trade-offs involved in a person's economic decision making?

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.
