  • 1 Ton of Refrigeration - Engineering Stack Exchange
    2 "1 TR is equivalent to the rate of heat transfer needed to produce 1 U S ton (2000 lbs) of ice at 32F from water at 32F in one day, i e , 24 hours " While defining 1 Ton of Refrigeration (TR), why doesn't some specific value of pressure come into definition?
  • Converting time constant to bandwidth of 1st order system
    When the system is first order: $1 (1+s\tau)$ Why is the bandwidth: $f_ {-3db}=1 (2\pi \tau)$? Where did the $2\pi$ come from? Why isn't it simply $1 \tau$? The unit of $2\pi$ is related to radian
  • What is GPS and TR in EMTP RV? - Engineering Stack Exchange
    The GPS signal is streamed at a 50Hz rate It is called NAV code The TR (transient recorder) or receiver can read its position off these NAV codes Then it connects the dots and draws a course line on a background map application like google earth or shipping charts or aviation charts or the proprietary maps NAV code source The entire Navigation message, the Master Frame, contains 25 frames
  • What specification describes best a bulldozer strength?
    Bulldozers are tracked-type tractors designed to push soil and heavy objects In a typical specification sheet, the following are listed: Flywheel power (hp or kW) Gross power (hp or kW) Engine
  • Interpreting roots of a cubic EOS with 3 phases (VLLE)
    1 Not anywhere near my area of expertise, but Wikipedia says of all cubic-equation-based equations of state that For Pr<1 and Tr<1, the system is in a state of vapor–liquid equilibrium The reduced cubic equation of state yields in that case 3 solutions The largest and the lowest solution are the gas and liquid reduced volume
  • Mean diameter of the collar when calculating the raising torque
    1 It's not possible to calculate the collar diameter from the thread dimensions The collar can be made any size greater than the thread diameter The bigger it is, the bigger the torque needed to overcome its friction, so the diameter can be important If you can show that collar friction is negligible, then discard it
  • measurements - Calculate shear stress unit conversions - Engineering . . .
    The formula: Tau=Tr J since I know the Maximum torque, the polar moment of inertia for a solid shaft, I should use the Modulus of rigidity from the material properties sheet for Tau then solve for the radius to get the diameter of the shaft Is that correct?
  • mechanical engineering - Gear Ratio of a Stepped Planetary Gearset . . .
    I was looking into planetary gearsets, and came upon the concept of a stepped planetary gearset In the image shown above, if my input was the blue sun gear, the output was the planet gear, and the
