Point taken of course,but over here we have a strict system regarding building sites involving safety and risk assessment training. To get on to a site you must have the appropriate licence or documentation, ie worker, machine operator, delivery, inspector or visitor. You then have...
It is my opinion that a vapour barrier actually contributes to cracking, the same as an overly wet subgrade would!Let me try to qualify! As you have already read other threads on this subject, I won't rehash too much, but I do find SCGeo's assessment interesting to say the least!If the...
ke6fx,I need to say it IS the contractors fault! The concrete mix is innocent! Everything that has been said is correct, however, if I could just put it into a bit more perspective.The cracking is shrinkage cracking [or alligator,although I haven't heard that term before, I'm from OZ] Yes, it...
Obssv, I hope that in the couple of days since your last post that you've had time to think a bit more about your theories! If not, lets work thru the first one. Steering head welded,cable attached to bike and a fixed point, bike perfectly vertical,now roll on the throttle and bike tries to move...
A "Rat Wall" is exactly that,it stops rodents burrowing under a slab from the edges. They are effective if that's a problem in your area.The rodents burrow under and excavate big areas of fill from under your slab to make a "home", effectively leaving it partially...
Not sure what that is! Do you mean the whole bike is weaving or are the forks misbehaving!Has it suddenly happened ? Just a thought, but are your wheels tracking properly and check that they are they both vertical, but the latter would suggest a bent frame!Other than your alcoholic content, I'm...
Interesting! Had the exact experience a couple of years ago with a Yam 660 "Aventure Tourer". Did an "Outback" {OZ} ride with four others on the same bikes of about 2500 miles in 7 days.Because the riding conditions would be varied and unknown, I decided to set my bike to the...
What effect does the profile/shape of a tyre have on steering a bike? For instance, my tyre is flat with rounded edges , and a sportsbike tyre is very rounded!
My last post may have been a bit confusing, but the spinning wheel was just a way of working through the gyroscopic theory put forward by Mowgli!I'm curious Mowgli, why your so sure it's gyroscopic, did you read it in a book? If so, and Metalguy is right, {pity his post was deleted}, then how...
The Police used to have a way, maybe xray, to find out if a motor had been stolen and the numbers ground off. Apparently the number punch compacts the cast iron below the imprint and the xray can detect it.I'm not sure tho wether it was just one of those urban myths!!
There is a gyroscopic action called"precession"{which Mowgli may have been alluding to} which basically means that when a spinning wheel{gyro}, has a rotational force applied to it, ie. turning your front forks,which is working in a horizontal plane, the wheel{gyro} will react by...
Okay, lets say your driving down a road doing 60mph in a car and turn the steering wheel to the right to go round a right hand corner, because it has 4 wheels it will simply go round the corner, but in the process it throws a lot more force on the left hand wheels,agreed!!Gyroscopic effect? I...
Scoobystu,once again an interesting spinoff to the question,and I'm not quite sure what forces are going on in some of the manouvres those guys get up to! I think tho, once you leave the ground the rules change,and while there might be some gyroscopic effects, the supercrossers are simply...
Your gyro in the sphere made me want to ask was it vertical, horizontal or somewhere in between!! Which then made me wonder whether a gyro knows which way is up, at all!! I re-read ICman's response and he stated that you need gyroscopic effect to right the bike after it leans! I don't think...
OK, maybe there is a slight gyroscopic effect, which obviously would increase with the speed of the bike,but perhaps no more than 10 percent.I say this because even with his front wheel spinning in the air the same as his back wheel he would probably only have slight "counter steering"...
Is it hypothetical? If so take the difference of the weight of the cables out of the equation and hanging parallel to each other, and the answer is equal!This was not arrived at by calculations, but by a simple practical experiment. Set up two scales ,two identical pieces of square tube a metre...
