1) How much stress will be generated in the 13mm diameter aluminum rod below with an increase in temperature of 30 degress C? - Look up the coefficient of thermal expansion and elastic modulus for aluminum (Sl units) in the book. - Calculate the temperature increase it would take for the aluminum rod to expand an contact the wall. - Subtract that number from the temperature change given to see how much of our temperature change will be after this contact and generate stress. - Calculate the stress generated in that rod due to that excess temperature increase. - Compare your answer: 13.89 MPa 0.5 mm- L = 1 m

The figure below is the basic plot of pressure vs. volume for the Dual Standard Cycle. Constant pressure heat addition 3 4 PV = constant %3D Heat IN Adiabatic expansion 2 Heat OUT (Constant volume heat rejection) Constant volume heat addition 1 Adiabatic compression Volume (V) Using the Dual Air Standard Cycle and the following data: • Assume constant properties of air. R= 287 J/kgK; Cp = 1005 J/kgK; Cv = 718 J/kgK; y = 1.4 • Cycle compression ratio = 14 (V1/v2) • Air conditions prior to compression: Pressure = 1.3 bar; Temperature = 293K • Heat added at constant volume = 280000 J/kg • Heat added at constant pressure = 662000 J/kg Pressure (P)

5. A container weighs 3 lbf when empty, 53 lbf when filled with water and 66 lbf when filled with glycerin. Find the specific gravity of the glycerin.

Need help with these two questions. for the first question please do the whole conversion process. And include all steps and units please and thanks
