Hi all - In the Near Eastern Late Bronze Age the Egyptians employed a two-man chariot with the axle placed at the rear of the vehicle; whereas the Hittites employed a three-man chariot with the axle placed in the center of the vehicle. As a result, the weight of the two-man crew in the Egyptian...

Hello. Lets say I am riding a unicycle rolling along the wheels direction with some velocity v0. I know that for the unicycle to turn a curve the centripedal force must be provided by the static friction with the rode that acts against any slipping of the wheel. I am however having trouble...

Hi All, I am doing analysis that has turned Categorical/Nominal data into Likert by conducting surveys asking for the perception of the level of "intensity" of a category. Example: In a category of management support, the category CIO shows up for meetings is turned into an interval...

Someone asked if it was possible to conduct electricity through a wire with a plasma. I ran across a article about a inventor who wanted to turn a antenna on and off very quickly. He said it was possible to do this by using a florescent light bulb as a element in the antenna. When a...

I am an apple grower and want to build trailers to haul apples (in bins) through my orchard. I want to couple 5 - 10 foot X 40 inch wide trailers (in tandem) and tow them through the orchard. The rear axel on each trailer is fixed and the trailer connects to the trailer in front of it (on a...

I want to know how much electrical power I could potentially generate by putting a generator at the pivot point of a rotating arm. I figured I can calculate the Kinetic Energy of the arm by: E=(Iw**2)/2 where I is moment of Inertia and w is angular velocity. I = (mL**2)/3 for a uniform rod in...

Hi, Someone tried to scam me a while back and they were stupid-enough to leave a message in my Android answering machine. Question: Is there a way of turning a phone message into a .wav, .mp3 or other type of sound file? I guess it depends on whether the message is stored in my end or in the...

Hi. I'm reading a solution to a problem concerning a gas of photons. In the solution, the energy of the gas is given as E=2\sum_{\vec{k}} \frac{\displaystyle \epsilon_{\vec{k}}}{\displaystyle \exp[\beta\epsilon_{\vec{k}}]+1} where \epsilon_{\vec{k}} is one photon's energy. It is said then...

Substitute teacher, Baraba Rose, convinced a class of kindergarden kids that she would turn into a bird before the school day ends. What is the probability that this event will take place? Solution: Let P = probability P(turning into bird) = 0 The answer is 0 because human beings cannot turn...

Does anyone know what will happen if the two front wheels of a car turn away from each other (left goes left and right goes right) while the car is moving or if they turn inwards towards each other? Other than the stress on the steering rod, will this cause braking and if yes, how effective can...

Homework Statement To what radius do you need to compress Mars in order to turn it into a black hole? Homework Equations None given, but I am mildly familiar with Schwarzschild and his equation. I know that if we double the object's mass, multiply by the universal gravitational constant, and...

Homework Statement A problem of practical interest is to make a beam of electrons turn a 90∘ corner. This can be done with the parallel-plate capacitor shown in the figure (Figure 1) . An electron with kinetic energy 2.0×10−17 J enters through a small hole in the bottom plate of the capacitor...

It's a huge problem for me, and only after turning it in, do I realize that I made a few mistakes; then I constantly worry about how that will affect my test score. Has anyone ever experienced this before? How would I cope with it? I don't think I would be able to deal with the stress of...

Homework Statement I am given the following figure: These are converging rays that appear to be going to a point F convert to a plane wave upon hitting the boundary between n2 and n1, and I am asked to find the equation for the boundary between n1 and n2 that perfectly accomplishes this...

Hi there, Suppose we had a car going in a circle. We know that the turning angle(angle between the movement direction and the wheel axis) and the friction are connected, because friction determines the centripetal force and it determines the radius of the circle that we make with our car. I need...

Hello everyone, My name is Ramon and I just had an idea. Do you think it will be possible in our time to turn elements into other elements? For example rearranging the atoms that make hydrogen or H2O into gold. The reason I was thinking of this is because if we can create a resource we can...

whats the turning point of (1-lnx)², x>2 is it a minimum or maximum. can someone help me

I am trying to understand what forces keep a free vortex, (i.e. a vortex ring). Its rotating particles must have a force to avoid them going out (like gravity on planets). I have read about vortices and vorticity, but get lost in equations. Is it possible to explain the force that keep the...

Hi was trying to figure out what would happen if you reversed the wing of a standard prop plane? for example...the thinner wedge is towards the front. Would you still get lift? I suppose not since there is a reason the rounded/thicker edge is facing towards the front. but why not?

Hi again. I hope this is the right section to ask this question. Not home work (I'm retired) but yet another mind game I'm playing (and still getting nowhere). I have trying to work out the formula for how a ski will perform a carved turn. I have looked at many (many Many) websites and they...

Hello everyone, I am not an engineer, so I apologize if this is a relatively simple question. What's the best way to turn rotational motion into linear motion under the following circumstances? 1. Rotational motion is driven by a vertical bolt. 2. When turned, the bolt will extend a bar...

Good day all I am struggling with this one. m (d^2 h)/(dt^2 )+k dh/dt=-mg use v=dh/dt in place to turn 2nd order into 1st order so from this i have got (d^2 h)/(dt^2 )= -g-(v/m) Is this a first order equation? If so can somebody point me to solve the equation when m=80, k=8.7, v(0)=0ms-1...

Let us first review Einstein’s train and platform thought experiment which consists of one observer midway inside a speeding train car and another observer standing on a platform as the train moves past. A flash of light is given off at the center of the train car just as the two observers pass...

Hi everyone, i hope this is the right place to post this. Anyway, I'm creating a game, and I'm trying to calculate and project future car movement path based on steering angle of the wheels. By using equation: r = wheelbase / sin(steeringAngle) I'm able to calculate turning radius. But the...

So last week I was returning from a holiday (by car) and on the way I saw a field with about 20 wind turbines on it. They were slowly turning, as usual. At first it seemed normal but I suddenly realized, by the open window of the car, that there was no wind at all. So I wondered if there was an...
