Assuming the coefficient of friction u = 0.05 for problem 7.13, calculate the oil temperature increase after1 [min] of operation. For simplicity, assume that all heat remains in the cam, follower and oil, that the coefficient of friction is independent of temperature, that the temperature of the cam, follower and oil is the same and that the total heat capacity of the assembly is C = 200 [J/K]. Assume that the cam and follower are adiabatic. (Ans. deltaT = 6°C)
