tensile specimen of the metal with gage length = 100 mm is stretched to a length = 157 mm. Determine the flow stress at the new length and the average flow stress that the metal has been subjected to during the deformation. Solution: ε = ln (157/100) = ln 1.57 = 0.451 Flow stress Y f = 850(0.451) 0.30 = 669.4 MPa. Average flow stress Y f = 850 ...

in the U.S.A. 3 mm 2/s oils became standard while, in the U.K., 7.5 mm /s oils were used. AeroShell Turbine Oil 300 and AeroShell Turbine Oil 750 respectively were developed to meet these two separate requirements. The situation persisted for some years until 3 mm2/s oils were required for use in British pure jet engines.
