I Calculating frictional heat from rotating mass

  1. Oct 21, 2016 #1
    How would one calculate the heat generated by a rotating body inserted into a different softer material? Similar to a drill bit, but without the cutting edges so a smooth constant profile across the probe surface.

    Hello Condiec, :welcome:

    Torque times angular speed gives the power put in; almost all of that will be converted to heat.

    It's comparable to friction work with linear motion: ##F \times v ##
