There are a lot of formulae "out there" to use for determining resonant torsional frequencies. I need the simplified formula that determines the resonant frequency for a system that can be simply modelled as two inertia discs (I1 and I2) connected by a shaft. Also... won't there be higher order...
Our company has a system as follows:
(1) A normally aspirated diesel engine displacing 92 liters with a maximum speed of 1800 rpm requires combustion air supplied at 25 deg. C and 70% relative humidity.
(2) This system requires (a) an air handling unit capable of supplying at least enough air...
I need to determine the exhaust mass flow through an exhaust system with only the following equipment available:
(1) UEGO based AFR sensor with the appropriate conditioning to measure the air-fuel ratio
(2) Compressed air supply with adequate pressure regulation equipment and a valve to meter...
I would like to know the effect of temperature on the tensile and ultimate strength of bronze alloys in general and UNS 67300 per BPS 4752 specifically.
I would like to know the effect of temperature on the yield and ultimate strength of bronze alloys; specifically UNS 67300 per BPS 4752... or anything in general.
I have been looking for the formula for alternating stress. It's the formula for fatigue analysis whereby "R" is the variable and ranges between R = -1 (full reversible stress; Fmin = -Fmax) and R = 1 (Fmin = Fmax... static load). The formula is some function of Fmin and Fmax but it is NOT (I...
I would like to know what's "out there" for stress concentration factors in splines. The closest thing I could find was in St. Peterson's book that deals with SCF's in gear teeth.
