    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.

  • 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.

  • 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.

  • Why do people still buy mechanical watches?

    "I don’t understand why anyone would buy anything other than a watch with a quartz movement. They an order of magnitude cheaper, require no maintenance, and keep much better time (they only lose or gain, at most, 0.5 seconds per day). The best mechanical watch gains or loses 3 seconds per day, making a quartz... show more
    "I don’t understand why anyone would buy anything other than a watch with a quartz movement. They an order of magnitude cheaper, require no maintenance, and keep much better time (they only lose or gain, at most, 0.5 seconds per day). The best mechanical watch gains or loses 3 seconds per day, making a quartz movement, by my calculations, six times more accurate. To me, this is analogous to people spending three times more money to purchase a slide ruler as opposed to a calculator. Before calculators were invented, slide rulers were common, and the high end of the market produced wonderfully detailed, intricate, and useful models (and they could get expensive, depending on the features). Today, calculators are cheap, easy to use, and much more accurate and precise than slide rulers. However, you don’t see people spending $200 on a slide ruler, bragging that it is a purely mechanical device and therefore contains “old world craftsmanship”. So why buy a mechanical watch? "

  • 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.

    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.

    Best answer: no. just be thankful you found a job, hopefully one you enjoy doing. many have a job just to pay the bills. as you said, you switched fields of study, so you had a later start towards your potential career anyway.

    you could always consider the military for careers too. the Army has their own Engineering unity, among other engineering jobs in all branches. and with your degree, you could apply and train to become an officer. or, just enlist and start out as an E-4.
