Steel beams are placed 10 ft on-center under a steel deck supporting a concrete fill floor. the plan dimensions for the floor are 20 ft by 60 ft. they must support a dead load of 100 psf and a live load of 50 psf applied to the floor area. determine the uniform load per foot of beam that each interior beam must support. assume one-way behavior.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

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?
