The mass fraction of eutectoid cementite in a hypereutectoid iron-carbon alloy (just below its eutectoid temperature) is 0.103. On the basis of this information, determine the composition of the alloy. If it is not possible to determine the composition from the information provided, enter 0.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length
