A developer is having a single-lane raceway constructed with a 100 mph design speed. A curveon the raceway has a radius of 1000-ft, a central angle of 30 degrees, and a PI station at 1125 10.If the design coefficient of side friction is 0.20, determine the superelevation required at the design speed. Compute the degreeof curve, length of curve, PC station, and PT station.

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?
