    The frictional torque resisting rotation of an angular contact ball bearingg builds up from rest to its steady value through a small but finite angle of rotation. A similar transient torque is observed when the direction of rotation is reversed so that, in a bearing which undergoes oscillating rotations of small amplitude, the resistance torque ...

    In addition, combustion efficiency varies between approximately 90% - 95% as load changes, having little effect on engine torque. Indicated thermal efficiency is also independent of engine speed. Likewise, the heating value, fuel to air ratio, density, engine displacement, and number of cycles per intake stroke are all independent of engine speed.
