    Drag coefficient for plate perpendicular to airflow

    Apologies, Did not properly read OPs question. I thought he was talking about parallel flow on plate. Whoops =)

    Stress Analysis - Annulus Circular Plate

    I'm doing stress analysis on a circular region on this part where an o-ring seals against. There is a 7500 PSI normal force being applied on it. So you can think about it as an annular circular flat plate (like a washer) with the 7500 PSI force uniformally distributed on the surface. I want...

    Engineering ball sorting project, static electricity

    The simplest solution to this problem would be to utilize their weights. They are of the same size but they differ in weight (even though not by much). You could perhaps use brush hairs carefully woven and fixed internal to a 11mm radius hole. The idea being that the heavier (Acetal) ball will...

    Maximum Temp. that a 2 NPT (Pipe Thread) can withstand.

    It depends on the material of construction of the pipe... Is it stainless steel? Temp rating will be high Carbon Steel? It will be a lot lower. Then you can look up a chart that will tell you the max temperature rating.

    Drag coefficient for plate perpendicular to airflow

    What are your flow conditions? Laminar? Turbulent? Are we just talking about ambient air? or God blowing on the plate... =) Give me the Reynolds number and I can help you out. Cheers =)

    Questions on the responsibilities of a mechanical engineer.

    I work in the subsea oil field. What you will do as a Mechanical Engineer will largely differ from one industry to another. If you work in an industry that deals with robotics, you will be doing as much electrical stuff as mechanical... including program, tuning PID controllers, structural...

    Engineering Circuit analsysis problem. Simple

    Homework Statement A device can be modeled using a current source in parallel with a resistor. This device was connected to a 5[V] voltage source, as shown in Figure P2.3a), and a current i5 of 0.93[A] resulted. The same device was then connected to a 4[A] current source as shown in Figure...

    Engineering Where Did I Go Wrong in Power Calculation for Circuit Homework?

    Ignore my last two responses. I did get the right answer but I have an issue with a statement you made. You said that, "find only two elements are sources, where the current flows from lower potential to higher potential. The rest are sinks, where current flows from higher potential to...

    Engineering Where Did I Go Wrong in Power Calculation for Circuit Homework?

    Actually I need one more thing clarified. Which current is flowing through Element C?

    Engineering Where Did I Go Wrong in Power Calculation for Circuit Homework?

    I did what you asked Vela. I flipped the Polarities of the Voltages that were given negative values and I switched the direction of current which was given negative values. Now I have another problem. You said that Developing Elements are where current goes from - >> + and Absorbing...

    Engineering Where Did I Go Wrong in Power Calculation for Circuit Homework?

    Homework Statement vT = 10.3[V], vW = -7.6[V], vX = -8.4[V], vY = -9.5[V], vZ = 1.9[V] iM = 3.3[mA], iN = 24.1[mA], iP = 15.2[mA], iQ = -18.5[mA], iR = 5.6[mA], iS = -8.9[mA] Homework Equations P = vi or P = -vi mA = miliamps The Attempt at a Solution Well I used the...

    Calculating Forward and Backwards error of the sine function

    NVM. I feel so retarded. I figured it out. Obviously it would be the inverse Sin(x) function that would allow me to calculate the backwards error.. SO obvious wow.

    Calculating Forward and Backwards error of the sine function

    1. The sine function is given by the infinite series sin(x) = x - x3/3! + x5/5! + x7/7! + ... a) What are the forward and backward errors if we approximate the sine function by using only the first term in the series, for x = 0.1, 0.5, 1.0? b) Using the first two terms. Homework Equations...
