Trans., 1894) investigated the question for the cases of loaded and unloaded shafts, and, owing to the complication arising from the application of the general theory to the cases of loaded shafts, devised empirical formulae for the critical speeds of shafts loaded with heavy pulleys, based generally upon the following assumption, which is stated for the case of a shaft carrying one pulley: If Ni, N1 be the separate speeds of whirl of the shaft and pulley on the assumption that the effect of one is neglected when that of the other is under consideration, then the resulting speed of whirl due to both causes combined may be taken to be of the form N1N2~!
They unloaded the wardrobe cart and sent it to take wounded men from a house two doors off.
Bianca cried out in surprise as Talon unloaded on Toni.
Corn from middle Russia for Astrakhan is transferred from the railway to boats at Tsaritsyn; timber and wooden wares from the upper Volga are unloaded here and sent by rail to Kalach; and fish, salt and fruits sent from Astrakhan by boat up the Volga are here unloaded and despatched by rail to the interior of Russia.
Let t be the statical breaking strength of a bar, loaded once gradually up to fracture (t = breaking load divided by original area of section); u the breaking strength of a bar loaded and unloaded an indefinitely great number of times, the stress varying from u to o alternately (this is termed the primitive strength); and, lastly, let s be the breaking strength of a bar subjected to an indefinitely great number of repetitions of stresses equal and opposite in sign (tension and thrust), so that the stress ranges alternately from s to -s.
