A cold drawn shaft of 1144 steel is loaded with alternating bending moment and steady torsion 202.2 N. m and 31.6 N. m., respectively. Use the information listed below to find the safety factor using modified Goodman failure criterion. - The small and larger diameters are 25 mm and 50 mm, respectively. - All transitions in the shaft are filleted with radius of 1 mm. - The shaft operates at room temperature - The reliability goal is 99.9

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
