Consider 6.0 kg of austenite containing 0.45wt% c and cooled to less than727°c (1341°) what is the proeutectoid phase? (b)how many kilograms each of total ferrite and cementite form? (c)how many kilograms each of pearlite and the proeutectoid phase form? (d)schematically sketch and label the resulting microstructure.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
