In the 1920... the closed body rose to dominance, the Model T came to an end, and the upgrading of cars began. The events of the past few years of ca… - Alfred P. Sloan

Roll a ball under your hand on a table and roll a pencil in the same manner. What you feel are "point" and "line" bearings. But to understand what mechanics mean by a surface "bearing," grasp a pencil in your hand and use your other hand to make it turn as a piece of shafting. Now, the lower half of the shaft is supported everywhere by contact with your hand — the upper half is not supported, merely covered. The advantages of ball and roller bearings were obvious many years ago to mechanical people... Solid steel rollers, being inflexible, were not satisfactory at that stage, but a Hyatt flexible roller bearing was different. We had something. Our spirally wound tube roller had a springlike quality, yielded to irregularities caused by poor manufacture, thus making automatic adjustments between housing and bearing.

I then went on to suggest that we make a serious effort to gauge the demand over the next five to ten years, and make plans to meet that demand. In building new facilities, I suggested that we "use corporation funds for such new plants needed for armament if that gives us better control over same from the long term position in relation to the master plan." Accelerated depreciation made the use of corporate funds all the more feasible, and relieved the government of the necessity of providing capital for the plants.

It is astonishing what you can do when you have a lot of energy, ambition and plenty of ignorance.
