Unformatted text preview: accompanying expansion and contraction of the metal causes the cylinder to rotate by creating a net torque. Work may be harnessed from this rotation. By Taylor expansion one may show the stress of the cylinder in the x direction is given by: d ( , 29 = ( , 29 + 1 (-29 + 2 (-29 , where x , L ,and T , are the normal stress in the x direction, the average length, and the average temperature of the cylinder respectively. Let a 1 and a 2 be constants. Draw an idealized x vs. L diagram (analogous to a PV diagram for a gas) for the cycle (that is, a full rotation). What would the actual diagram look like qualitatively (sketch this on your previous diagram and explain your answer). ChemE 3130 Chemical Engineering Thermodynamics Problem Set #5...
