Ashaft is loaded in bending and torsion such that ma 5 70 n ? m, ta 5 45 n ? m, mm 5 55 n ? m, and tm 5 35 n ? m. for the shaft, su 5 700 mpa and sy 5 560 mpa, and a fully corrected endurance limit of se 5 210 mpa is assumed. let kf 5 2.2 and kfs 5 1.8. with a design factor of 2.0 determine the minimum acceptable diameter of the shaft using the (a) de-gerber criterion. (b) de-asme elliptic criterion. (c) de-soderberg criterion. (d) de-goodman criterion. discuss and compare the results.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
