Steady-state creep data taken for an iron at a stress level of 131 mpa are given here: ? ? (h^�1) ? [mpa (psi)]6.3*10^-4 10708.8*10^-2 1210if it is known that the value of the stress exponent n for this alloy is 8.6, compute the steady-state creep rate at 1290 k and a stress level of 86 mpa. (answer is in h^-1)

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
