2. Sketch a dislocation loop in the form of a circle and specify the Burgers vector of the loop. Denote the portions of the loop that are edge and those that are screw. Given that edge and screw dislocations have somewhat different energies per unit length, would you expect dislocation loops generally to be circular in shape

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
