...prime motor, said the lecturer, is an instrument taking its energy from nature and applying it to the uses of man. All mechanical tasks are done by the overcoming of resistance; in fact the overcoming of resistance is the definition of work...
...latest of Ericsson's inventions was his sun motor, by which the rays of the sun are utilized to heat a steam boiler. Although this motor is not now in use, still it must be regarded as one of the most important inventions of Ericsson's life...
...night, J. C. Powers '92 was elected to membership. The speaker of the evening was Lieut. J. B. Cahoon from the Thomson Houston Works. With him came several former members of the club now at work in Lynn. The subject of the discussion was the new slow speed car motor. This was described in detail and photographs of the various parts were exhibited. By the new arrangement 10 per cent. less current is required to do a given amount of work, and a speed of forty miles an hour can be obtained. The coils are also placed out of danger...
...A.ZOOLOGICAL CLUB.- There will be a meeting of the Zoological Club this evening at the Museum. Doors open from 7.15 to 7.30. Papers will be given on Amitosis in the Salamander, by H. P. Johnson; on Epidermal Rods in Turbellarians, by W. M. Woodworth; on Fibres of the Ocular-motor Nerve, by G. H. Parker, and on Development of the Earthworm, by C. B. Davenport...
...motor is a dynamo reversed, the current going into the coil and causing its revolution. Power is commonly transmitted in this way with an efficiency of 74 per cent. of the power applied. Since the current always equals the pressure divided by the resistance and a man's resistance is about 2000 ohms, he cannot take more than a quarter an ampere from the 500 volt current of the street railway, whereas 10 amperes are necessary to kill. Interesting and convincing statistics were cited to prove the number of deaths from electricity almost nothing compared with those from all other...
