• Will distilled water destroy electronics?

    Distilled water conducts electricity a lot less than regular water. The way that I understand that water destroys electronics is by short circuiting it. Does that mean if I have an electronic with a low enough voltage that I can submerse it in distilled water and it'll still work? does that also mean if I have... show more

Does that mean if I have an electronic with a low enough voltage that I can submerse it in distilled water and it'll still work? does that also mean if I have an incredibly low voltage electronic and submerge it in water that it'll be ok?

  • Why do cars have 4 wheels?

    Best answer: It's a compromise of stability, cost, and weight distribution. Technically, three would suffice, but they would tip over more easily. Too many wheels increases friction as well, but often multiple pairs of wheels are necessary in case of heavier vehicles such as trucks. Friction isn't always bad, mind you.... show more

Too many wheels increases friction as well, but often multiple pairs of wheels are necessary in case of heavier vehicles such as trucks. Friction isn't always bad, mind you. It is good if you want the vehicle to brake suddenly, but it is bad if you are after maintaining better fuel efficiency.

  • What is the right degree for me (philosophy of /deep engineering kind of thing)?

    Best answer: At this stage you can't do much better than physics in terms of getting to the root of things, and if you can combine that with a vocational degree such as comp. eng. then so much the better. Depending on where you study there may courses that deal with the philosophy of science etc. but these will add nothing... show more
    Best answer: At this stage you can't do much better than physics in terms of getting to the root of things, and if you can combine that with a vocational degree such as comp. eng. then so much the better. Depending on where you study there may courses that deal with the philosophy of science etc. but these will add nothing to your employability and there is a danger that they become a self contained world of arguments that is divorced from actual science, if you don't already have a good grounding in undergraduate level modern physics.

    Engineering is subject specifically aimed at people who want to make things that work. In an ideal world it would be completely underpinned by a full theoretical understanding, but practically with limited time for learning, it is more useful (for making things that work) to learn more stuff that directly affects your ability to make things that work, and so this replaces various bits of science that may not be necessary to know as an engineer.

    This year I am taking biology and because it is an honors class I am required to make a science fair project. It has to include a bit of biology and engineering. As my friend is into building robots and I am into surgery we have decided to build a robot that can cut open a body with more accuracy than the human hand. As this is a science fair project and not an actual thing that cost millions of dollars to produce, around how much will it cost? We want it to not be too expensive. We also have access to a laser cutter and a 3d printer.

    Best answer: Probably about the same length of time. The process of cutting the stone has not changed that much in the past years.

    Our bits are stronger and won't wear out as quickly...but it's still chipping away at the stone.

    The only thing that would be easier is the fact that we would have faster ways of surveying the site to know where and how deep to cut.

    So...maybe a decade.

  • Will spraying metallic paint in a flashlight reflector make it brighter?

    Best answer: Metallic is not smooth, therefore it will absorb some of the light instead of reflecting it. You need a gloss finish silver. Or if it's a serious restoration, have the reflector chrome plated.

    Best answer: We see the videos. We draw our own conclusions.
    Not speaking about Grenfell tower, but another concrete tower in Las Vegas that burned in the upper stories for 2 weeks. Building is still standing.

    The Trade Centre towers were built to EXCEED the building standards...in earth quake, in high winds, and even if an airplane hit the thing. All were factored into the calculations. It had an abundance of redundancy built into it. The building was noted to be built of steel pillars and window glass was in combination for its strength.

    Jet fuel burns at 800F It is a cold burn. It needs pure oxygen to burn hotter. It smoked...meaning lack of oxygen...and burning colder as it burned wood desks and fabric.

    Jet fuel is not some magical fuel. It is diesel/or kerosene. Extra refined but very similar to the fuel for diesel vehicles or kerosene lamps.

    -structural steel begins to soften around 425°C and loses about half of its strength at 650°C

    You will see the numbers and do the comparison
    (most people do without looking at the measuring scale) Fuel burns at 800. steel softens at 650.
    one is in Fahrenheit and the other in Celsius(they got tricky here)and equate the 2 temp scales as being the same. They are far from it.

    So lets make it all Celsius. So we are comparing apples to apples

    800F is now 427C. Now the steel is just hot metal.
    Window Glass(as the structures were made of steel and glass) softens at 800C. Not all the windows broke.(800C is the low range as it could be 1000C on glass when it is starting to get soft.)
    .This is the information on the web regarding the melting point of steel beams
    .the melting point of window glass
    .Gypsum don't melt or burn and is strong when pushed on the edges.
    I am not even figuring with concrete yet. Concrete would be used on the floors...so pancakes. supported by steel beams and glass throughout the structure.
    Sure, there may have been some upright concrete posts(floor to ceiling)or a concrete tube for the elevators is common would go up many floors...and around the stairwells which is why they call it a well.

    The temperature is a long ways from 650C which would soften the steel to half the strength.
    At even half the strength because of the amount of redundancy built into the structure, there is no way in hell that could have collapsed especially starting 3/4 of the way up...like there is nearly no weight above it. The jet became instantly just fuel on the floors. The engines from the plane have a weight which can be found on Google and that is sitting like a display of several big cars the floor. The rest of the plane weighs next to nothing...being aluminum.

    So I have ruled out softening steel and softening window glass, rumbling drywall, crumbling concrete stairwells and concrete elevator shafts.


    You made an error in your initial statement. Building 7 was slated for controlled demolition. It had explosives placed where they needed to be placed so it would fall into its own foot print. You can see the rate of fall of a controlled demo. and compare it to Tower 1&2. It is the same.
    . The plane striking the building did not cause the building to tilt over. It was like a bug hitting the windshield of the car or just did a "SPLAT".

    Amazingly the week before the owners of the building got a multibillion dollar insurance policy on both buildings specifically in case an aircraft hits it and the buildings go tumbling down. "Like they did" so the owners collected the insurance money.

    The Towers were in financial hardship at the time, too with many of the floors empty...so no rental money.

    When you do the arithmetic you can see this was an inside job...not some goat herders who could not fly a Piper Cub let alone a Jumbo Jet and do some flying that all trained pilots cannot do, then the question of whether it was a plane that hit the building or a missile.

    So many questions and no answers as the government cleaned up the mess and shipped it all away to be reprocessed overseas. All the evidence is gone.

    Much went on that was not normal procedure.

    But right away, FOX news was claiming who done it...even before the White house had a report.

    It was a government scam.
    I look at the FACTS without emotions getting in the way.
