    Single Phase vs. Three phase

    Thanks for all of you help gentlemen. In answer to rbulsara's question, the motors typically are 2 horse power on the size mill I am looking to purchase. This milling machines motor will experience some load when machining steel.

    Single Phase vs. Three phase

    I have two machine tools in my little machine shop. A milling machine wired 230 3 phase with a phase converter, and a lathe wired 220 single phase. I want to add another milling machine but it is wired 220 single phase. Or I can purchase a more expensive mill wired 230 3 phase. My question is...

    fatigue limit

    First we need to know what the shape is, second, we need to know what the yield strength is, third we determine yield strength if the material is heat treated, fourth how is it loaded? Is it a static load (no movement just constant pressure)? (or incremental pressure?), or is it dynamic...

    Developed Lengths Formula

    Send me an e-mail at keene.machine@verizon.net. We can get you the chart you need but going the eng tips forum is a pain in the a---! I'll make a .pdf of it for you. I don't think this chart will work for plastics as plastic don't tend to bend very well. However with the proper technique, one...

    Measuring Sound Waves

    I used the word "sonar" to get action on the thread only. The measurement is not taken in water but in air. Of the frequency in Hz insted of power as above I stand corrected. Greg is the link to the "sonar equation" the same for "in-air" measurement? Ray or Greg...

    Measuring Sound Waves

    I need an adequate formula that can be used to determine the distance a sound wave will travel where the following are known: Power in KHz that's used to drive the wave, the peak to peak echo measurment in Millivolts out, tested in 10 foot increments. These units of measure were taken using an...

    Solving for "Delta L" -L

    I have a piece of cured 2 part Thermoset #104 material that has a tensile capacity of 2,850 psi. It measures .5 x.5x1.4" I want to know how many pounds of force I can load it with. The load would be placed in the center of the 1.4" length at .7". A piece of steel will be placed on...
