@@jaysondoster9729 Clarkson you moron you've destroyed the Hillclimb car and to prove what "wind matters" now we have a massive bill and can't do the rest of the show.
I honestly love the fact that this can all be tested in BeamNG because it's that close to realism that you can see real world physics effects in the game. So freaking awesome
Ive been a skateboarder my whole life and I love how it teaches you about physics and science and how a slight change in path or speed or weight can drastically change the outcome of a jump or flip. This reminded me of that.
Pinewood Derby track design have changed a bit over the years and it demonstrated some of this phenomenon. In the '60s they started out steeper and leveled off about 1/2 way. As a Cub Scout I had a car that was very underweight, but had very little friction in the axles. It would be behind at the end of the slope, and then pass the heavier cars on the flat, as it lost speed much less than the heavier cars did. As I got older and had children, and an engineering degree, I did the complete MgH=1/2Mv² calculations (including the wheel inertial energy) to determine where to put the center of gravity. Fun times.
Red had the seccond best initial acceleration, so while the others where still building it, red was already rolling. The problem with the one with highest acceleration was the bump that killed every possibility to win.
to do this properly scientifically he would have to have had the red cars in parallel, so they were both pulling only the SUV, now the front car was pulling both the SUV and the other red car
It's mostly due to traction. The SUV is likely to have wider tyres and even if they aren't, the SUV puts all of its weight on driven tyres whilst the 200BXs put some of their weight on unpowered tyres. Whilst torque does play a role, once your tyres start slipping all the torque in the world won't save you
It would also have been more "equal" if the vehicle of choice was a RWD SBR4 because it's rear engined. So the majority of the weight is on the driven wheels. OR any FWD car in reverse.
I thought for sure the two red cars would win, but thinking about it some more the SUV had double the power but not double the wheels. I think what made the difference was that there was more weight per driven wheel so more grip.
That makes a lot of sense. Perhaps if the drive wheels were located in the center of their respective cars rather than the rear, it would have been more even.
I'd really like to see how accurate the aero is in this compared to like a professional flow simulation software. See if it's generally accurate ad well as how accurate it is locally (basically as you get closer and closer to the body of the car.
Im pretty sure beamng doesnt simulate airflow, just thinks of a wing as any body feature, exept it "simulates" its surface area and angle to get downforce. Removin headlights, bumpers and so on have no effect on aerodynamics sadly
@@AndreBrah that's what's great about beamng. It does simulate these things. If your car doesn't have a windshield, for example, it will be slowrr do to the increased drag from the interior.
The red one makes sense, as it is very logrithmic with a fast drop, but then smooth transition to the change in direction. The sudden change in direction is what ruins the blue ramp. Interesting to see yellow,s performance with full throttle - I suspect it is the vehicle drivetrain/gearing that is to play there, and using different vehicles may change that outcome. I can spend hours fooling around in BeamNG tehehe, never gets old. Awesome video as always!
Having the cars use their own power in addition to gravity is similar to rotating the whole setup more steeply. In that configuration, the new brachistocrone is closer to yellow, and the old red curve is unnecessarily deep.
When you went to full throttle, I assumed yellow would win. Gravity is still the dominant factor, especially because shifting times fuck up your acceleration when boosted this much by gravity, but the yellow car has the second best assistance from gravity while having a more gradual slope allowing it to put down more power and push itself farther. I assume the red vehicle was mostly limited by shifting times and 2nd most limited by traction due to following such a perfect curve.
Just curious because i didn't see you to over it in the last test, do the two rwd cars have the same tires and tire size as the awd car? And is the torque half as well as the hp? Also, does the torque curve match?
@@novathepug6692 weight transfer isnt even a factor. Sitting still, the red cars have literally half the traction per drive wheel of the SUV, because while both has 4 drive wheels, the red cars have 4 rollers that take half of their weight. For the SUV any weight transfer would be transfering from one drive wheel to another, so its total traction would remain the same. For the red cars, weight transfer would slightly improve their traction, as the tug of war would shift SOME of their inertia to the back, but it would need to transfer literally ALL of their weight to even match the SUV. Given all 8 wheels were firmly planted, thats obviously not happening. It also straight up wouldnt happen at all with the red car in the back, cuz any weight transfer from tugging the chain would be canceled out by the car in front tugging on IT. Even if the red car in front was doing a wheelie, that would only give the red cars 75% of the traction of the SUV (because as mentioned, the weight transfer of the rear car cancels out)
The SUV won the last one because it has higher ground pressure. Think about it, 2400kg with 4 tires is 600kg per tire. 2400kg with 8 tires is 300kg per tire. This means that the SUV would have greater downwards pressure (and therefore better traction). You can see how the 200bx tires are slipping because they can’t get as much grip.
It happened to be faster because of gravity. The more vertical the angle, the gravity pull force be much bigger, and it helps to accelerate the object faster. Remove the gravity, and do it again with the same line graphic, object with the shortest line tend to be the number one to finish the race. (Yeah without gravity, the car wouldn't be able to move in the road. So TEST #2 need to change the object with airplane or space shuttle instead)
how smooth were those curves in the beginning? i noticed from the first person perspective the brachistochrone ramp seemed a little bit bumpy which could definitely cause enough speed loss to lose by about a foot. because in theory at least (meaning if there was no friction) you have the force of gravity and if each object now has an added force with the forces being identical (because they are the same car) the vehicle that won with no added force should win with the added force
Not necessarily, because the roads do not have the same length. So, let's say we ditch gravity and only use their motors. The green car would be fastest, then the yellow one, then maybe blue and only then red. Now adding 1% of gravity's pull, the result would barely change. Then 5%, you'd see changes but not enough to turn it around. Then a bit more and a bit more, until you reach a point where the red and yellow car basically go equally fast.
The tug of war one is difficult because it come down to grip more than anything and the dynamics of two cars stuck together also is weird in nature. Plus it is more about torque than horsepower. Fun experiment nonetheless! 😂

aerodynamic experiments are so cool in beamng, i love how cars can fly
Red had the seccond best initial acceleration, so while the others where still building it, red was already rolling. The problem with the one with highest acceleration was the bump that killed every possibility to win.
That's why we fly planes AGAINST winds, to give us LIFT! Great video, pal!
That "Go" sound clip gave me chills I haven't played that game in years man 😂
The tug of war experiment is down to torque though isn't it?
Yes and no, it's mainly traction. You can see that the tires of the smaller cars are spinning instead of gripping to the ground.
to do this properly scientifically he would have to have had the red cars in parallel, so they were both pulling only the SUV, now the front car was pulling both the SUV and the other red car

That makes a lot of sense. Perhaps if the drive wheels were located in the center of their respective cars rather than the rear, it would have been more even.
The only thing that mattered in the end that SUV had all of its weight on driven wheels, while the cars had only half.
Yup, it's all about traction. There are Videos of ATV winning tug of war against cars with much more power.

In the jump test, it would be interesting to see what a reasonable headwind would do. Here the wind was just too strong to allow the car to fly
I'd like to see what a medium crosswind would do to the trajectory.
