For general reading, nothing compares with the scientific and technical journals, which are now so replete with all kinds of information. Beside noting the present progress of engineering industry in all parts of the world, they contain nearly all besides that a learner will require. It will be found that information of improvements and mechanical progress that a learner may gather from serial publications can always be exchanged for special knowledge in his intercourse with skilled workmen, who have not the opportunity or means of reading for themselves; and what an apprentice may read and learn in an hour can often be " exchanged" for experimental knowledge that has cost years to acquire. (1.) Into what two divisions can a knowledge of constructive mechanics be divided ?—(2.) Give an example of your own to distinguish between special and general knowledge.—(3.) In what manner is special knowledge mostly acquired ?—(4.) What has been the effect of scientific investigations upon special knowledge ?—(5.) What is meant by the division of labour ?—(6.) Why have engineering tools been less changed than most other kinds of machinery during twenty years past ?— (7.) What is meant by machine functions; adaptation ; construction ? —(8.) Why has the name "mechanical powers" been applied to screws, levers, wedges, and so on ?—(9.) Can power be conceived of as an element or principle, independent of mechanism ? CHAPTER IL MECHANICAL ENGINEERING. This work, as already explained, is to be devoted to mechanical engineering, and in view of the difference of opinion that exists as to what mechan...« less
