question number 10.34 and 10.35

10.34 Steady-state creep rate data are given in the following table for nickel at 1000C(1273K) : If it is known that the activation energy for creep is 272,000J/mol, compute the steady-state creep rate at a temperature of 850C(1123K) and a stress level of 25MPa. 10.35 Steady-state creep data taken for a stainless steel at a stress level of 70MPa are given as follows: If it is known that the value of the stress exponent n for this alloy is 7.0 , compute the steadystate creep rate at 1250K and a stress level of 50MPa
