The shaft is roughly .58 inch/14.7 millimeters in diameter near the grip and between 35 and 48 inches/89–115 cm in length. Shafts weigh between 45 and 150 grams depending on the material and length. Graphite shafts are woven from carbon fiber and are generally lighter in weight than steel shafts. Graphite shafts became popular among amateurs ...
Solheim began PING golf as a garage business in 1959. His frustration during the game of golf resulted from his difficulty putting with the equipment of the era. The engineer from General Electric invented a new putter in his garage known as the "PING 1A". Instead of attaching the shaft at the heel of the blade, he attached it in the center.
When an element of mass is offset from the axis of rotation, centrifugal force will tend to pull the mass outward. The elastic properties of the shaft will act to restore the “straightness”. If the frequency of rotation is equal to one of the resonant frequencies of the shaft, whirling will occur. In order to save the machine from failure ...

Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. The resulting fault if alignment is not achieved within the demanded specifications is shaft misalignment, which may be offset or angular. Faults can lead to premature wear and damage to systems.
The essential difference is that the Satake diagram of a real semisimple Lie algebra with Cartan involution θ and associated Cartan pair = (the +1 and −1 eigenspaces of θ) is defined by starting from a maximally noncompact θ-stable Cartan subalgebra, that is, one for which () = and is as small as possible (in the presentation above ...
The following stresses are induced in the shafts. Shear stresses due to the transmission of torque (due to torsional load). Bending stresses (tensile or compressive) due to the forces acting upon the machine elements like gears and pulleys as well as the self weight of the shaft. Stresses due to combined torsional and bending loads.
