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.
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.
(D) Threaded shaft A rod end bearing , also known as a heim joint (North America) or rose joint (UK and elsewhere), is a mechanical articulating joint . Such joints are used on the ends of control rods, steering links , tie rods , or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect alignment ...
The J Golf Phoenix LPGA International, in full the J Golf Phoenix LPGA International Presented by Mirassou Winery, was a women's professional golf tournament in Arizona on the LPGA Tour. Founded as the "Sun City Classic" in 1980 , [ 1 ] it was held annually in the Phoenix area through 2009 , making it one of the longest-lasting events on the ...

Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
The crankshaft is a rotating shaft containing one or more crankpins, [1] that are driven by the pistons via the connecting rods. [2] The crankpins are also called rod bearing journals, and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block.
Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to safely ignore it. Analytically computed values of eigenfrequencies as a function of the shaft's rotation speed. This case is also called "whirl speed map". [4] Such a chart can be used in turbine design.
