A manifold having a distinguished affine structure is called an affine manifold and the charts which are affinely related to those of the affine structure are called affine charts. In each affine coordinate domain the coordinate vector fields form a parallelisation of that domain, so there is an associated connection on each domain.
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 ...
Ping, Inc. (stylized as PING) is an American sports equipment manufacturing company based in Phoenix, Arizona. It focuses on golf equipment , producing golf clubs and golf bags . The company was founded by Karsten Solheim , following a career as an engineer at the General Electric company.
A muscle back is the more traditional design and consists of a solid metal head, typically made of forged iron. The design of the club typically distributes the metal more evenly around the clubhead (though most designs still place more weight along the sole of the club), which makes the center of mass of the club higher and the moment of inertia (the clubhead's resistance to rotation) lower ...

Let :, (,) be a (left) group action of a Lie group on a smooth manifold ; it is called a Lie group action (or smooth action) if the map is differentiable. Equivalently, a Lie group action of G {\displaystyle G} on M {\displaystyle M} consists of a Lie group homomorphism G → D i f f ( M ) {\displaystyle G\to \mathrm {Diff} (M)} .
[1] [6] Pitching over an obstacle is used in situations where a hazard of some sort, usually a water hazard, bunker or tree, is located in the line of the shot between the ball's current location and the target (often on the putting green). By utilizing a lob wedge for these short shots, the ball is carried much higher in the air than with a ...
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.
