Y is it important to "bank" a corner if a vehicle is moving at high speed-like racetracks & offramps-help!!!

On a flat curve, the centripetal force on the car is merely the friction between the tires and the road. Note, however, that this friction is STATIC friction, which has a maximum value. \n\nF(radial)=f(static)=mv^2/r\n\nIf the velocity exceeds a certain value, the car will slide. \n\nOn a banked road, however, one component of the normal force will point inwards, adding to the centripetal force. This allows the car to take the curve at higher velocities without sliding:\n\nF(radial)=f(static)+normal*sin(angle)=mv^2/r

I agree....remember, thats why people race manual cars. Because they want speed not torque..Common sense right

Why wouldn't you make an Tempo into a race car?...It's the perfect sleeper, and like it or not, I've seen quite a few made to race...\n\nDid you change the Onboard Diagnostic System?...Because it should be OBD-I...

The Ninja, Attack Squirrel Of Death!!!\n\n I never dreamed slowly cruising through a residential neighborhood could be so incredibly dangerous!  Studies have shown that motorcycling requires more decisions per second, and more sheer data processing than nearly any other common activity or sport. The reactions and accurate decision making abilities needed have been likened to the reactions of fighter pilots! The consequences of bad decisions or poor situational awareness are pretty much the same for both groups too. Occasionally, as a rider I have caught myself starting to make bad or ate decisions while riding. In flight training, my instructors called this being "behind the power curve". It is a mark of experience that when this begins to happen, the rider recognizes the situation, and more importantly, does something about it. A short break, a meal, or even a gas stop can set things right again as it gives the brain a chance to catch up.  Good, accurate, and timely decisions are essential when riding a motorcycle.at least if you want to remain among the living. In short, the brain needs to keep up with the machine. I had been banging around the roads of east Texas and as I headed back into Dallas, found myself in very heavy, high-speed traffic on the freeways. Normally, this is not a problem, I commute in these conditions daily, but suddenly I was nearly run down by a cage that decided it needed my lane more than I did. This is not normally a big deal either, as it happens around here often, but usually I can accurately predict which drivers are not paying attention and avoid them before we are even close. This one I missed seeing until it was nearly too late, and as I took evasive action I nearly broadsided another car that I was not even aware was there!  Two bad decisions and insufficient situational awareness.all within seconds.  I was behind the power curve. Time to get off the freeway.   I hit the next exit, and as I was in an area I knew pretty well, headed through a few big residential neighborhoods as a new route home. As I turned onto the nearly empty streets I opened the visor on my full-face helmet to help get some air. I figured some slow riding through the quiet surface streets would give me time to relax, think, and regain that "edge" so frequently required when riding.  Little did I suspect.  As I passed an oncoming car, a brown furry missile shot out from under it and tumbled to a stop immediately in front of me. It was a squirrel, and must have been trying to run across the road when it encountered the car.  I really was not going very fast, but there was no time to brake or avoid it-it was that close.I hate to run over animals.and I really hate it on a motorcycle, but a squirrel should pose no danger to me. I barely had time to brace for the impact.  Animal lovers, never fear. Squirrels can take care of themselves! Inches before impact, the squirrel flipped to his feet. He was standing on his hind legs and facing the oncoming Valkyrie with steadfast resolve in his little beady eyes. His mouth opened, and at the last possible second, he screamed and leapt! I am pretty sure the scream was squirrel for, "Banzai!" or maybe, "Die you gravy-sucking, heathen scum!" as the leap was spectacular and he flew over the windshield and impacted me squarely in the chest.  Instantly he set upon me. If I did not know better I would have sworn he brought twenty of his little buddies along for the attack. Snarling, hissing, and tearing at my clothes, he was a frenzy of activity. As I was dressed only in a light t-shirt, summer riding gloves, and jeans this was a bit of a cause for concern. This furry little tornado was doing some damage!  Picture a large man on a huge black and chrome cruiser, dressed in jeans, a t-shirt, and leather gloves puttering maybe 25mph down a quiet residential street.and in the fight of his life with a squirrel. And losing.I grabbed for him with my left hand a

I always do, because its annyoing when there is a spot but a cart or two is in the way....they also roll and damage cars (victim of this). It's lazy people who don't, and that's annoying. And those who are saying its not laziness, then why don't you put yours away?

When you turn a sharp corner in your car (say going around and round a circle) the rear wheels must travel "different" distances.  The inner wheel is on a smaller circle than the outer wheel.  If both wheels were connected to a fixed axle and were locked to rotate together, one or both wheels would have to slip on the pavement to make up for the different lengths in their paths.  This would increase tire wear and affect handling and braking.\n\nThe differential gear system allows the two wheels to move at different rotary speeds while both still receive power from the engine through the drive shaft.  See the link for details and a good illustration.  BTW, this is not a problem for the front wheels which are used for steering because they rotate independently and are not driven by a fixed axle and drive shaft (except in front-wheel drive!).

Remember that there is friction acting on the car from the movement of the wheels over the road. Work must therefore be done to overcome this friction.

Practice, prefereably with non brakable objects to represent other cars - cardboard boxes and traffic cones.\nI found it helped to visualise the car from outside but some people think i'm crazy.

It is dangerous..but I understand the sport..I think they need to have more  legal 1/4 mil tracks available for public use...

I think you are right; it isn't fair. For distance races you are probably going to pass people on the curve anyway but it DOES matter like you said. I think it matters a lot in the 4 by 4. I always hated running the 2nd leg because I would have to run a couple extra feet and it would add on to my time :(. But just try not to worry about it because you are going to end up running a few extra feet anyways if you want to pass someone. God luck in track!

track took some rain this weekend. It was probably sealed and will be speed biased. play front runners

It keep the tires warm and enhances the car's traction when the green flag drops.  The tires are made to operate best a race speed, so when they are just following the pace car they can cool to less than optimal temperatures.  Forcing them to corner increases the friction acting on the tire and generates heat.  Well, that sounds good anyway, right?

Zero.  The whole point of active suspension is to anticipate bumps and dips at the incipient time that the wheels encounter them so that no disturbance is experienced by the passengers.  The "read ahead" of the road needs to take into account the vehicle speed and the response time of the system actuators so that the wheel is being pushed down at precisely the time it enters a pothole.  Otherwise, it's going to be like the hydraulic systems on some low-riders.  Similarly vehicle speed, actuator response time, and steering input need to be accounted for to preclude roll. (lateral rotation caused by centrifugal force.)

I have never seen anything like blueprints. We have made tracks, and they always evolve as you build them, and as you use them. I'm guessing you are going to use dirt, so just keep fooling around in your space and see how you want the turns, and how tight they should be. Learn how long of a stretch your go cart needs to get to top speed, and make your straight aways about that long. Also, if you are going to do jumps, add them after you have built the track, and put them in places that are easy for people to pass on, that always makes it more interesting.\n\nI would seriously just keep foolling around until it makes sense.\n\nHave fun.

in most places, pedestrians have the right away so they think you have to stop for them.  This is the wrong thought.\n\nI just speed up....that teaches them to look next time.  Unless of course, I hit them.

You can't without the radius of the wheel...m/s is a tangential speed.

The stop distance is not an arithmetic progression (ie it is not 40m). It is in fact a geometric progression. The stop distance is a lot lot more. Truthfully, I don't know but if you were travelling at 120 kmh and there was a truck 40m (or even 60m) in front of you when the brakes locked; you'd be dead.
