  • Probabilistic Estimation of the Effect of Dimensional Tolerance for Turbine/Compressor Blade Attachment (.pdf)
    in the root attachment area is a function of geometry, material and tensile load. Tensile load is a function. of the speed of rotation. Figure 1 shows an idealized structure with load on the root and a reaction force on the. upper hook. It is difficult if not impossible to write a closed form solution
  • Dimensional Change Comparison of Materials with Different Microstructures
    alloys due to. oxygen sensitivity. Advances in sintering & powder production technology have made it possible. to successfully utilize chromium and manganese and take advantage of their attributes [4]. Figure 1. The effect of various alloying additions on hardenability according to Metals Handbook
  • What Is a Go / NoGo Gage?
    tolerances will be new to some readers, it may be helpful to know what they are called in the language of the machine shop. .001" one thousandth (of an inch). .0001" one tenth (of a thousandth). .00001" ten millionths. .000001" one millionth. Using this vocabulary, then, the figure .00012" is read
  • Using Microchip's Micropower LDOs
    . accuracy is not specified because it depends on the. external feedback resistors. Figure 1 shows a typical. Table 1 shows that percentage of total output voltage. adjustable LDO feedback circuit in which resistors R1. error contributed by the tolerances of VREF and R1/R2. and R2 set the output voltage
