  • Why a pile of concrete cubes is seen before construction of a road bridge?

    Why a pile of concrete cubes is seen before construction of a road bridge?

    I have seen this many times. Before start of construction of a road bridge, there is always a huge pile of concrete cubes placed on the side of the road. It is removed within a day or two. Is it some sort of stress test?

  • Could anyone suggest magnets that can held GI pipe strongly?

    I need a magnet that can held GI pipes which has weight 10 15kg and 20 to 30 kg. In one of my project currently working, needs to held a pipe mechanically. So, I was thinking if I can use magnets that can do my job.

  • Where are the positive and negative poles of the AC/DC adapter wire (as shown in the picture)?

    Where are the positive and negative poles of the AC/DC adapter wire (as shown in the picture)?

    Best answer: Look closely at the end that plugs into the wall - it should have some info printed on it. First, make sure it has a DC output and that output is the correct voltage and sufficient current for your use. Then if you look closely, there should be a symbol that looks a bit like the letter "C" with a dot in... show more
    Best answer: Look closely at the end that plugs into the wall - it should have some info printed on it. First, make sure it has a DC output and that output is the correct voltage and sufficient current for your use. Then if you look closely, there should be a symbol that looks a bit like the letter "C" with a dot in the middle. It will indicate the polarity of the output. Commonly, the center pin (the 'dot') is positive, and the shell ('C') is negative, but that is not always the case.

  • What is the stored Energy in AC capacitor - AC or DC ?

    Best answer: The energy "stored" in the capacitor fills and empties 100 to 120 times a second. If you disconnect the capacitor at just the right instant, then it may be charged to the peak line voltage, 1.4 times the RMS voltage, which corresponds to an energy of CV^2. "AC" is just a sine wave voltage.... show more

    "AC" is just a sine wave voltage. "DC" is a voltage with a constant offset in one polarity or the other. Capacitors in AC circuits are used to create a phase shift and never accumulate a charge since the average value of a sine wave is zero.

  • If I insert a solid, light weight wooden pole very tightly inside a hollow aluminum pole of the same length...?

    will the aluminum pole become much more rigid? Both poles will be 6 feet long. I have thought of an interesting method for accomplishing this task. Or will the aluminum pole just rupture?

  • What does dx/dt mean?

    Best answer: d is shorthand for Delta which represents change. Example: If x is initially 5 meters and becomes 10 meters. then dx is the difference: 10-5 = 5 = dx dt is the change in time. If you start measuring when the clock reads five seconds and stop at 10 seconds then the change in time is 5 seconds = dt dx/dt = 5 meters/5... show more
    Best answer: d is shorthand for Delta which represents change.
    Example: If x is initially 5 meters and becomes 10 meters. then dx
    is the difference: 10-5 = 5 = dx
    dt is the change in time.
    If you start measuring when the clock reads five seconds and
    stop at 10 seconds then the change in time is 5 seconds = dt
    dx/dt = 5 meters/5 seconds = 1 meter/second

    Meters per second represent velocity just like Miles pet hour.
    dx/dt allows you to use any units of distance and time with the
    same meaning as velocity.

    For calculation purposes this becomes convenient.
    If V = dx/dt, then dx/dt = acceleration × time
    and integrating x = 1/2 at²

    You'll get it with a little help from YouTube's treatment of
    SUVAT.

  • Why does deep frying fat/oil turn into stubborn grease?

    Best answer: Oil molecules contain multiple double bonds which react at elevated temperatures (Diels-Alder and free radical reactions). These create polymers of the already high molecular weight triglycerides.
