thanks for the help, yes i mean that little fin. I was just wondering the implication and use of having this little fin. What it does for the aerodynamics etc. If it useful for aerodynamics, why don't all engines have it? What makes the trent need it and the others to do without it?
The strength of the turbulence is directly proportional to the temperature of your coffee
A chart is presented for the coefficient in the formula for the critical compressive stress at which cross sectional distortion begins in a thin-wall tube of rectangular section symmetrical about its two principal axes. The energy method of Timoshenko was used in the theoretical calculations required for the construction of the chart. The deflection equation used in this method was selected to give good accuracy. The exact values given by solution of the differential equation were calculated for a number of cases and it was found that the energy solution was correct to within a fraction of 1 percent. The calculation of the critical compressive stress at stresses above the elastic range is also discussed. In order to demonstrate the use of the formulas and the chart in engineering calculations, several illustrative problems are included.
