During rotation for 9 = 45°, the cam's profile completes the displacement of the fol-
lower for a distance h. Calculate the maximum allowed value h which provides the
condition where the pressure angle a does not exceed the permitted value a max = 20°;
calculate the profile angle 0* at which the pressure angle becomes worse.
