I'm pretty sure you've gone through the same thing as I did... Now, when you jump your car in BeamNG and try to steer left or right, you will feel the car moves slightly (still mid-air) ... Does anybody know why ? I know that the car changes its pitch when braking due to inertia and stuff going on in the brakes but I couldn't know why the first thing happens. Is it like sitting on an office chair and trying to spin it without touching the ground (friction)? It might be a tiny bug in Torque 3D engine or it could be a real thing. your thoughts ?
What Zappy said, and the fact that steering the car physically moves the wheel nodes, thus causing equal and opposite reactions.
You mean because they were spinning on the ground and turning them mid-air (while still spinning) will cause the gyroscopic effect to change slightly ? Edit: I looked it up and found this video. At 0:55 he explained it Thank you mouse and snake wait .... mouse and snake lol Here's what I understood. hope u dont mind the bad quality drawing
Excuse my hazy physics knowledge (high school physics was quite a while ago...). Ever picked up a powered-on external hard drive? The rotating platters inside are essentially a gyroscope. Due to its high rotational speed, it carries a lot of inertia; i.e. requires more energy from an external force to move it around, and conversely applies an equal amount of energy to the body moving it around (Sound familiar? That's Newton's third law). However, it only applies to forces that act to change its rotational axis, which is why it doesn't feel heavier or more difficult to push around on a flat surface, but seems to slightly resist when you tilt it. The correct reasoning behind it is not something I remember, so do a little research on that. Same principle applies to the front wheels: The wheels are each a gyroscope, and you turning the steering wheel applies a force that acts to change their rotational axis, which, according to Newton's third law means they must apply an opposing force to the vehicle itself, rolling it slightly in mid air. That's probably right, but if somebody more comfortable with physics would like to correct or elaborate upon my points, that'd be great.
Precession may be the term you are looking for zappy? My understanding/ability to explain is also limited.
Try drving a car off a cliff or bridge going really fast, then slamming on the brakes. The wheels will stop instantly taking all the forward rotational momentum from the wheels and stopping it. That energy goes somewhere, the brakes. The brakes are attached to the car body and a few calculations with weight transfer later and you got your car tilting forwards. A few ways you could use this is one canyon of speed for example, keep the car floored after you take the jump, if your leaning too far back hit the brakes, and if you lean too far forward accelerate, if you are leaning to the left turn to the right and leaning to the right turn left. Best demonstrated with the sbr4 because of its light weight, great speed and quick reactions.
I agree with zappymouse. My Professor at the university used to demonstrate those forces while sitting on an office chair. He held a bycicle wheel with both arms streched in front of him. When he tilted the spinning wheel to either side he was able to rotate the chair without touching the floor. Made a hilarious picture seeing an old man having fun that way Besides: I love Beam.NG exactly for this kind of depth in physical details!
