The interest rate is one of the most important way by the
monetary police for achieving its economical goal and raising
growth rate, it effects on banking activity by accepting deposits
and giving loans, which mean that harmonic between the
struc
ture of banking deposits and loans give a needed support to
investment, production and income to reach the stability
economic.
To show the relationship between interest and growth rates, we
have to aware the various effectives of inflation and population
rates on real growth, so we study it by using statistical system
SPSS.
The main objective of this article is to study the influence of static and dynamic
behavior on the occurrence of contact fatigue on spur gear tooth. For this end, a dynamic
model of geared transmission in one degree of freedom, with Crossland crite
rion, are used.
The motion equation is analyzed step par step in the time in order to determine the
dynamic load in all contact points on teeth profile. In this way, the time-varying dynamic
loads on tooth flanks are determined and the subsurface stress components can be derived
from the classic Hertzian theory.
