THREE:These divisions of machinery will next be treated of separately, with a view of making the classification more clear, and to explain the principles of operation in each division. This dissertation will form a kind of base upon which the practical part of the treatise will in a measure rest. It is trusted that the reader will carefully consider each proposition that is laid down, and on his own behalf pursue the subjects farther than the limits here permit.(1.) What kind of strains are shafts subjected to?(2.) What determines the strength of shafts in resisting transverse strain?(3.) Why are shafts often more convenient than belts for transmitting power?(4.) What is the difference between the strains to which shafts and belts are subjected?(5.) What is gained by constructing a line shaft of sections diminishing in size from the first mover?(6.) What is gained by constructing line shafts of uniform diameter?
