A mechanical model in the form of a gyroscope may be made to simulate the path of an electron in a uniform magnetic field acted upon by transverse electric fields. In using the model, one employs the following substitutions: The uniform magnetic field is replaced by the spin velocity of the...
Laue photographs of aluminum‐rich aluminum‐silver crystals during aging at 20° and 150°C show more or less clearly defined streaks along certain zonal ellipses, in addition to the streaks caused by thermal agitation. These have been analyzed by stereographic and reciprocal lattice...
This paper describes the results of an investigation and extension of the various proposed procedures and methods of analysis for the photoelastic determination of three‐dimensional states of stress. Two important limitations of the previous developments are removed. A true extension to three...
The Reynolds theory is applied to the calculation of the lubrication properties of plane sliders—thrust bearings—of infinite width provided with lubricants whose viscosities increase exponentially with the pressure. The friction coefficient, minimum film thickness, and lubricant flow were...
The ratio of watts to volt‐amperes does not give the power factor of long cables because of the resistance of the conductor and sheath. The error involved varies as the length squared and might be quite appreciable at lengths of 10,000 feet. Correction factors are given involving the use of an...
