Determine the wall loading that can be carried by a long footing 1.2 m wide and located 1.5 m below the ground surface. Strength testsindicate that the soil has a cohesionof 58 KN/m3and angle of internal friction of 20O. The total soil unit weight is 19 KN/m3. The soil above the footing is well compacted, and depth factor will apply. The soil rigidityindex is greater than the criticalindex. Use a factor of safety to 3 with the extended generalbearing capacity equation,

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?

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
