Tens years of experimental trial proved how much accurately an ordinal person can establish the geometry constructions and wheel alignment on general car.
Precisely established ground level. And automobile can move antero-posteriorly to release and open the internal stress in rubber materials, bushes and tires.
Avoiding spot distortions on the tire surfaces, the pressure was increased to the maximum 3kg/cm2. Unless this preparation, obtained datum differ considerably with no repeatability, it's because reduction of height invites increase of camber value due to supporting point goes outside.
Actually useful device for vertical inclination for camber measurement.
1719,75mm radius pendulum device was invented to read 2minutes on 1mm distance value.
For horizontal measurements, LASER equipped device is popular, but remember here, the measurement point should not be prepared on wheel surface but on vertical hub circle surface. The reason is that wheel manufacturing accuracy permitted 1mm error on their production.
Possible to keep Japan as an independent country without US assistance?
Neighbours are so sly and sturdy as to throw us difficult problems as if they were suffered from our failures.
Now the time is come to show clearly that the problems are not for our side but only caused by themselves.
Now peaceful group had known about the the necessity of military power like harvest needs water of rice field.
How shall we do in future, only argument in the party can unable to solve this problem.
