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

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

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
