    Hydrodynamic or Hydrostatic Bearing?

    Sorry, I forgot to mention that it is a thrust(axial) bearing. Basically the fluid enters through center of the bearing and is pushed out radially through slots between the pads of one side of the bearing. The maximum pressure difference that the bearing experience is about 1.03 bar (15PSI). In...

    Hydrodynamic or Hydrostatic Bearing?

    Thank you for you reply. Basically, I am describing a hydrodynamic bearing, which is running in an environment where there is a pressure drop across it. Hence, I am wondering what would be the correct way to model it. I am aware that usually hydrodynamic bearings have oil supplied at a low...

    Hydrodynamic or Hydrostatic Bearing?

    I am working on a machine with a hydrodynamic bearing that is located in an an area that has a varying pressure drop across it depending on the situation, in other words the pressure of the fluid going into the bearing varies, while still being higher than the pressure of the fluid going out of...

    Strain Gauges and Heat

    Thank you for all of your answers. The strain gauge is used to measure torque. One of my problems is that the strain gauge was attached to the component by a third party company. I asked them about the possible effects of heat to the assembly and their reply was: You can expect a zero shift of...

    Strain Gauges and Heat

    I have a problem with my strain gauge (load cell) measurements being affected by heat. I contacted the manufacturer of my strain gauge and they claimed that it is only affected 0.01% per degrees C. However, this is significantly less than what I am experiencing. Has anyone had similar problems...

    Easier way to declare matrices

    Currently in my calculations I declare the initial conditions as an overly long matrix, which is difficult to fit on the page, 30 rows. I am therefore wondering if there is a more compact way to declare a matrix, or perhaps to be able to convert a vector into a matrix? My matrix basically is...

    If statements for matrices

    I am quite new to Mathcad, and am wondering if there's a simple way to run 1D matrices through if statements. Currently the if statement just complains about the variable not being a scalar, and doesn't therefore process the variable. Thank you.
