• Should I finish my engineering degree if I have no interest in engineering?

    I just failed first year (passed only four courses). I'm taking tuition now and quickly realizing that I have zero interest in calculus and physics. But I think that if I continue I will be able to pass the courses and eventually get the degree. I am just doing it to get a high paying job. I have no interest in engineering, but at the same time I have no interest in anything else either and don't know what to do with my life. I am really confused and I don't want to disappoint my parents.

  • Is wood with vents a bad amplifier enclosure material?if so why?

    Hi I am building an basic amp(its only 100watt 2 channels) with a tone board.I would like to make the enclosure /cabinet fully with wood.but its usually not recommended as wood is not good at heat dissipation.what are other cons of using wood as enclosure? What are your opinions?

  • If i was using an electric motor to charge a battery, how would i stop the motor from spinning because of the battery?

    Best answer: Rectifier. It won't let the current go the other direction. You could also try disconnecting it.

  • Why do people still buy mechanical watches?

    Best answer: slide rule, not slide ruler. I know because that is all they had when I was in college 40 years ago. But I got the first TI calculator as soon as it was introduced, about 1970 or so. Same story for quartz watches when they were introduced. I agree with you, the technology of electronic watches is far beyond... show more

    I agree with you, the technology of electronic watches is far beyond mechanical versions. Some people must feel a kind of prestige paying thousands for a wind-up Rolex watch.You can try luxurywho.com with good quality.

  • Will airlines go out of business due to rockets pilot shortage?

    Best answer: Even if they do develop commercial passenger carrying rockets. I don' think that will eliminate passenger planes. Rockets work best for very long flights while various planes are made to fit all types of flights.

  • Light Switches that do the same function, how do they work?

    Okay, so I have these set of stairs, at the top there's a light switch to turn on the lights for the stairs, but at the bottom there's one that does the same job.

    Okay, so I have these set of stairs, at the top there's a light switch to turn on the lights for the stairs, but at the bottom there's one that does the same job. I have forgotten which order they go in, mostly because I'm slightly autistic and I worry about things, but I didn't know what exactly to google because I don't really know the name of these types of light switches. My main concern is, am I overloading the electrical source when I have one light switch on and one off and vise versa? Or does it not matter? I've never really been a genius in electrical engineering so it would be great if someone could maybe tell me how they work. Thanks.

  • Please help with this math question?

    Please help with this math question?

    Best answer: More an engineering than a math question since unstated conditions related to the nature of cantilever beams and rigid supports are needed to solve the problem.

    y" = k(L-x)² = kL² - 2kLx + kx²

    Integrating to find the slope of the deflected beam::
    y' = kL²x - kLx² + kx³/3 + C.
    Assuming a rigid connection at the base, the slope of the beam, y'(0) = 0 → C = 0
    y' = kL²x - kLx² + kx³/3

    Integrating to find the deflection of the beam::
    y = kL²x²/2 - kLx³/3 + kx⁴/12 + C
    Again, assuming a rigid connection at the base, the deflection of the beam, y(0) = 0 → C = 0

    The maximum deflection occurs at the free end of the beam, x = L
    y(L) = kL⁴/2 - kL⁴/3 + kL⁴/12 = kL⁴(6-4+1)/12 = kL⁴/4

  • Why are the requirements so high for engineering positions when the work is typically so mundane?

    I think a big part of my problem is companies can sense I don't put up with BS well. I should enjoy being boring work that is my problem.
