A two dimensional photoelastic study of the load distribution among the roller bearings in a rock bit
The photoelastic technique was employed to investigate the adverse affect on the load distribution among the roller bearings in a rock bit cutter as a result of the relatively large radial clearance in the bearings. A ...
An experimental and analytical investigation of the effect of tray liquid on the vibration behavior of bubble towers
Study of field observations indicates that tray liquid affects the vibration behavior of a bubble tower as would a tuned dynamic vibration absorber. In this thesis an analytical investigation and experimental model studies ...
Design of nozzles for partly ionized gases
An analytic expression is obtained for the speed of sound in a partly ionized gas under certain conditions. The method of characteristics is adapted to use this information for the solution of the compressible gas flow ...
The effect of vibrations on ordering in a copper-gold alloy
Experiments were performed to determine the effects of mechanical vibrations on ordering in CuAu. The effects of 5, 10 and 15 kc vibrations were investigated over a range of ordering temperatures of 280 to 360°C. A retarding ...
Effect of vibrations on the yield strength of a low carbon steel
Experimental results show that, when a specimen is subjected to vibration in the frequency range from 15 kc to 80 kc, the steady stress necessary to cause plastic deformation is appreciably reduced. This reduction is ...
The ultrasonic measurement in nitrogen, carbon dioxide and nitrogen-carbon dioxide mixtures at medium pressure and temperature
Velocity of sound measurements have been made in pure nitrogen, pure carbon-dioxide and mixtures of these two gases at a constant pressure of 50 psi over a temperature range from 75°F to 530°F. From the experimental data ...
