Asteel chimney 30 m high has an external diameter of 1.8 m and is 35 mm thick. the wind loading is equivalent to a horizontal force of 1.2 kn per square meter of projected area. if the chimney is rigidly anchored at its base, calculate the maximum stress induced in the steel at the base. take the density of the steel to be 7 850 kg/m^3.

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.
