THREE:Boring may be called internal turning, differing from external turning, because of the tools performing the cutting movement, and in the cut being made on concave instead of convex surfaces; otherwise there is a close analogy between the operations of turning and boring.

THREE:CHAPTER I(1.) Why have belts been found better than shafts for transmitting power through long distances?(2.) What are the conditions which limit the speed of belts?(3.) Why cannot belts be employed to communicate positive movement?(4.) Would a common belt transmit motion positively, if there were no slip on the pulleys?(5.) Name some of the circumstances to be considered in comparing belts with gearing or shafts as a means of transmitting power.
