D5is it possible to produce an iron–carbon alloy that has a minimum tensile strength of 620 mpa (90,000 psi) and a minimum ductility of 50% ra? if so, what will be its composition and microstructure (coarse and fine pearlites and spheroidite are alternatives)? if this is not possible, explain why.(3 pts)

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.
