In contrast, while the swinger has some other advantages that the hitter does not have, the swinger wouldn't have the advantage of a "prestressed" clubshaft - because the nature of the physics is different- the "pulling" on the shaft in this context creates a "bowing up" of the shaft- not a "bowing forward" of the shaft that happens when one is pushing/hitting.

It is interesting that Homer said the Swinger's Clubshaft is also stressed, but during the change of direction at Start Down.

Even though the "bowing up" effect does bend the shaft, it is not regarded as a prestressed Clubshaft? So the term prestress refers to the stress placed on the shaft in only one dimension? There are lots of Swingers with a bent shaft at Impact, but this is obviously not what Homer was getting at.
