Today we'll talk about the strength of the body, measure the length of the wires and count the number of parts from which you can assemble a car. Some of the facts may seem strange or absurd, but each is interesting in its own way.
Fact 1: A suspension bridge can be woven from the wires of your car
Electrical wiring is the nervous system of a car. Signals run back and forth over wires of different lengths and cross-sections - from the blinking of the turn signals to starting the engine and the operation of the ABS. The more modern and more expensive the car is, the more wires it needs. Options like active suspension, an audio system with a bunch of speakers or a starry sky roof all contribute to the overall power grid. So it turns out that a modern Mercedes-Benz S-Class or Porsche Panamer can hide up to three kilometers cables. The budget Logan is also not an outsider: the total length of its wires is definitely enough to power a light bulb about 800 meters away from you.
You can also surprise the owners of the "antiquity". So, the total length of two hundred electric cables of the first VW Golf is almost equal to the height of the main building of Moscow State University. One has only to unwind …
Fact 2: It takes the Hulk's strength to twist the car body by a degree
Body rigidity is a key indicator of vehicle safety. Usually they talk about torsional stiffness, that is, the ability of an automobile body to maintain its shape under the influence of a large torsional moment. For example, when hanging on a slope. For your Vest, the value will be: 18,000 Nm / deg. Is this a lot? Imagine that the rear suspension of the car is fixed, and a one meter long lever is attached to the points of the front. In order to "spin" the body one single degree, at least 18 thousand Newtons of force must be applied to the end of this lever. Or hang a whole Jaguar F-Pace on it neatly! Remind me, who can raise Jaguars here?
By the way, the body rigidity of the F-Pace itself reaches 22,000 Nm / deg. And to hear the crunch of a carbon monocoque Bugatti Chiron with an indicator of 50,000 Nm / deg, our Hulk will have to team up with Thor.
Fact 3: Your car can become a Tesla at any time
It's about driving a starter. In the old days, motors were started with a curved lever, which required a lot of effort. Today, an electric starter the size of a loaf of bread is in charge of the launch - and it does so quickly and effortlessly. This thing seems to be strong. But how much?
Let's just say - strong enough for the car to travel 30–40 meters on pure electric traction; without gasoline or with a stalled engine. To do this, the starter will have to be tormented - on cars with "mechanics", turn on the first gear and turn the engine longer than usual. Together with it, the wheels will begin to rotate. Such an "electric car" cannot go far, since starters are not designed for long-term operation. But you can leave the intersection or remove the stalled car from the railway crossing. Alas, this option is not available to owners of automatic boxes.
Fact 4: It only takes a car half a teaspoon of fuel to start.
If we forget for a second about the harsh Russian climate and the capricious Zhiguli engines, then to start a modern engine, about two milliliters of fuel must run through the cylinders. Of course, this amount is not enough for a full-fledged work, so do not be greedy. Moreover, half a teaspoon of "ninety-fifth" in today's prices is some 10 kopecks.
Fact 5: There are small blast furnaces under the hood of the car
The heat inside the working motor is well above a hundred degrees Celsius.When the working mixture is ignited, the temperature in the cylinders rises to 2500 degrees, which is enough to melt aluminum, iron or cast iron. Theoretically, the motor could melt itself, but this does not happen - due to a clever cooling system that removes a large amount of heat. In addition, the duration of one stroke of the working stroke (when the flame of the burning mixture pushes the piston down) is too short. So forget about the tiny home foundry.
Fact 6 Thousands of cutlery can be made from a cylinder block.
However, you can try to melt the motor itself. For example, the four-cylinder block of the VAZ Grants is enough to make 45 cast-iron pans. Or 1,500 spoons for a very spacious dining room. And if you take a used Hyundai Solaris engine, then there will be a lot more spoons, and they will all be aluminum. Thanks to the alloy block.
Fact 7: To assemble a copy of Logan from Lego, you need 10 times more parts than for a real car
It would seem that the plastic element of the construction kit is much larger than the nut or contact of the wiring of your car. And the average car has already been assembled from more than thirty thousand different elements - from large to very tiny. Five thousand of them are in the engine.
But if you try to create a life-size Lego copy, you will need hundreds of thousands of parts. For example, a plastic Volvo XC90 on a one-to-one scale contained 201 thousand elements. The Chevrolet Silverado pickup, indistinguishable from the original, is already 334 thousand, and the McLaren Senn sports car, identical to the natural, demanded nearly 468,000 "cubes". Ten to one …
