Determine the maximum permissble value of P if the alowable bending stress is 40 MPa in tension and 70 MPa in compression

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

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

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
