By how many degrees will a copper plate with an area of S = 12 cm2 heat up when cutting a thread in it with a pitch of 0.75 mm, if during cutting a moment of force of 4.9 Nm must be applied to the driver? The specific heat capacity of copper is 376 J/kg deg. The density of copper is 8.8 g/cm3. Assume that all the heat generated is received by the plate.
