Worksheet provided by your instructor to document your answers. 1. A weight of 20,000 lb. is supported on a rectangular base plate that is 8 in. wide
and 3 ft long. The base plate rests on a concrete slab. Determine the stress that the
base plate exerts on the concrete slab. Express your answer in units of (a) lb/in.2
and (b) lb/ft? (precision of 1 for (a) and of 1000 for (b))

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

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?
