A 1 inch diameter bar machined from AISI 1035 CD Steel is subjected to an alternating bending stress between 1 and 51 kpsi at 400 C. Find the factor of safety guarding against static failure and either the factor of safety guarding against a fatigue failure

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
