Determine the in-plane normal and shear stresses along the seam of the tank of Problem 6.16 if it is helically wound at an angle θ = 60°.
Problem 6.16:
Determine the maximum in-plane stresses for a cylindrical tank made of steel (E = 205 GPa, ν = 0.30), having a mean radius of 2 m and a thickness of 20 mm, and subjected to an internal pressure p = 1 MPa.
a piston-cylinder device contains 4.53 kg of refrigerant-134a at 1200 kpa and 60 degc. the refrigerant is now cooled at
A piston-cylinder assembly which initially has a volume of 1 m^3 is filled with 0.7 kg of air. The pressure on the air is always maintained at 1.2 bars. Heat transfer is allowed to take place until the volume is 60 percent of the initial value. You m..
(Hint: Use the RISKBINOMIAL function. However, if your model requires more RISKBINOMIAL functions than the number allowed in the academic version of @RISK, remember that you can instead use the CRITBINOM function to generate binomially distributed..
