No inferiority complex

There exist many barriers and difficulties to measure wheel alignment and axle construction for ordinary person who do not have Special tools and devices and most of the people will give up to do by ourselves at all. Wheel alignment tester machinery is expensive and it is difficult to handle and master it. This is why this specific field "Alignment" is ignored and regarded as the things impossible.
It is true that my imagination might be too childish and too primitive to measure and adjust the difficulty.
Remember that the Principle and the Aspect of change in Scientific field do not fluctuate so far as it happens on the Earth.
But the ideas of Trigonometric function and Pi would solves this Chronic problems to be cut in.
In addition, some principles of the Physiologic property of Viscoelasticity that is contained in the rubber material and lubricant.
Also the idea and understandings are required, Hysteresis phenomena of them and co-efficiency of friction between the tire and the ground surface.
Manufactures defines the tolerance in wheel alignment and axle construction based on the datum through their experiments and developments.
My intention is to minimize the assembly tolerance and the put them at the centric position.
Most of the challenger might give it up and run away to his tent, but the satisfaction when it is accomplished is above words.
Though my car is old with many clutches, dents and color balds, I never have any inferiority complex if some newly sophisticated, shiny and expensive one comes across to me. Because mine is well adjusted  and well maintained by myself in no relation with external appearance.
