Tony Posted June 20, 2006 Report Share Posted June 20, 2006 Can you summarize a consequence of this image..... The road is straight... RWD.... Extrapolate what consequence would result from this steering position, and why?.... just for fun You can also invite additional parameters, to encourage different results from the same example.

jon Posted June 20, 2006 Report Share Posted June 20, 2006 Is the car moving away or towards us? If it's moving towards us it looks like it's about to turn off the road. Quote Link to comment Share on other sites More sharing options...

At speed.... extrapolate the steering action? Quote Link to comment Share on other sites More sharing options...
discount tyres dan Posted June 20, 2006 Report Share Posted June 20, 2006 what about the other front wheel? Quote Link to comment Share on other sites More sharing options...
Tony Posted June 20, 2006 Author Report Share Posted June 20, 2006 what about the other front wheel? Opposite of the visible wheel.... Traveling toward you at speed.... Extrapolate the consequence for the visible steering position. Quote Link to comment Share on other sites More sharing options...

Tony Posted June 20, 2006 Author Report Share Posted June 20, 2006 This ? Slight camber issue there Mark!.... But no the image displayed is a moment in time, could you offer an explanation to what will happen next?.. all parameters have been realized... what is going to happen?

Mark H. Posted June 20, 2006 Report Share Posted June 20, 2006 If they are both pointing in by that amount will it not keep going forward until turned? I was mowing the lawn earlier and noticed that tyre on the drivers side. When you let of the gas whilst in gear my dads car makes a horrid noise like grinding. Wasn't sure if it was the diff, i was thinking of taking it to the shop for him as he went on the train instead rather than put another 500 miles on it. I wonder where nearby does geometry alignment . Quote Link to comment Share on other sites More sharing options...
Tony Posted June 20, 2006 Author Report Share Posted June 20, 2006 Ok This example suggests an extreme condition. Since the road is straight and we have established the car is traveling at speed, we can assume the steering position will develop a reply... summarize from this imaginary example how the car would react if it was also braking?

Continued:- So far we have Extreme lock RWD At speed Under braking Lets add Front engined Front Cambers at -1 degree each Rear Cambers at -30 minutes each What do you feel would happen to this car.

Dunno what they mean......... This club is crammed with information that makes sense of those numbers and respected forces ..... you are on the right track though Additional information. When the front wheels turn on a lock the Camber positions move to opposites, so the wheel in view would have a positive position, but as described it is under hard braking...... Oh and by the way 'star a' your post was the 4000th in wim Quote Link to comment Share on other sites More sharing options...

'Star a',stay with it you are nearly there! Lets add a parameter and summarize The attitude of the steering violent position (visual) The camber compression (now opposite) The inertia (Theoretical) The Geometry positions (Factual) The Kinetic force (Theoretical) The Roll centre (for Debate) Remember this example is for fun (factual) so 'No one' is wrong Quote Link to comment Share on other sites More sharing options...
discount tyres dan Posted June 23, 2006 Report Share Posted June 23, 2006 bet the car doesnt feel safe to go over 5 mph anyway, all feel will have been lost and maybe a lot of vibration too Quote Link to comment Share on other sites More sharing options...
Tony Posted June 23, 2006 Author Report Share Posted June 23, 2006 bet the car doesn't feel safe to go over 5 mph anyway, all feel will have been lost and maybe a lot of vibration too Remember the position you see is a (moment in time) All the parameters are visible and the car is traveling at speed.... Nothing is bent, what you see is the steering position -ver- the descriptions listed above. Analise the parameters, forces in all four dimensions, then extrapolate the outcome Quote Link to comment Share on other sites More sharing options...

Ok seemingly we still have some work to do understanding this Geometry lark....... Last chance... From all the parameters above extrapolate what is going to happen...... Then i will conclude with my thoughts to see if you agree..... I may be wrong Quote Link to comment Share on other sites More sharing options...

Lesson over.

IanF Posted July 8, 2006 Report Share Posted July 8, 2006 I'm new to this, other than knowing that there is something wrong with my cars setup but that the local garages don't know how to fix it. So from the picture.... Steering wheel looks to be straight. Suspension looks unloaded Perspective makes judging the tyre's direction difficult. It could be straight ahead. So:- the car just went airborne and is about to land with a bump? Quote Link to comment Share on other sites More sharing options...

Your car..... what's wrong?.... start a new thread and lets see if we can conclude your problems.... also you are immediately able to post pictures here in wim, so if this helps you then please do.
