Calculate the translational energy difference, in cm-1, between the 3,3,3 and the 4,3,3 energy levels of a oxygen molecule confined to a cube with sides equal to 1.0 mm. The isotope mass, in amu, is 15.9949. The force constant is 2293.8 N m-1

Calculate the translational energy difference, in cm-1, between the 1,1,1 and 2,1,1 energy levels of a nitrogen molecule confined to a cube with sides equal to 1.0 mm.

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.
