The downward foce applied at the 3rd pin is 20kn
the .4 measurements are in meters
link ab is to be made of a steel for which the ultimate
normalstress is 450mpa. determine the cross-sectional area for
abfor which the factor of safety will be 3.50. assume that thelink
will be adequately reinforced around the pins at a andb.

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.
