This also needs to be a consideration when comparing battery types of similar power descriptions, as often the longer the hourly rate the more efficient a battery will operate, so a 20 hour discharge will most likely produce a higher Ah rating than a 10 hour discharge period.
His model, the pentad, can be used to understand or interpret human behavior and to develop ideas for stories. The pentad assumes people can have ambiguous, conflicting, and complex reasons for acting. It attempts to avoid simplistic explanations.
The purpose of a trackbar is to prevent movement of the axle/wheels from side to side. The adjustable trackbars will keep the axles centered (left to right) under the vehicle once lifted. Think of it as a right triangle. The axle is the base of the triangle, and the trackbar is the hypotenuse (diagonal line). If the vertical rise changes but the base does not, then the hypotenuse (the track bar in this case) would have to change or be adjusted to compenate for the new vertical height. If the trackbar is not adjustable then the axle will shift more to one side and no longer be centered under the vehicle.
