There are several types of splines: [2] Parallel key spline where the sides of the equally spaced grooves are parallel in both directions, radial and axial. Involute spline where the sides of the equally spaced grooves are involute, as with an involute gear, but not as tall. The curves increase strength by decreasing stress concentrations.

The involute gear profile, sometimes credited to Leonhard Euler, [1] was a fundamental advance in machine design, since unlike with other gear systems, the tooth profile of an involute gear depends only on the number of teeth on the gear, pressure angle, and pitch. That is, a gear's profile does not depend on the gear it mates with.
Rounded shoulder posture (RSP), also known as “mom posture”, [1] is a common postural problem in which the resting position of the shoulders leans forward from the body’s ideal alignment. [1] Patients usually feel slouched and hunched, [ 2 ] with the situation deteriorating if left untreated.
Form diameter is the diameter of a circle at which the trochoid (fillet curve) produced by the tooling intersects, or joins, the involute or specified profile. Although these terms are not preferred, it is also known as the true involute form diameter (TIF), start of involute diameter (SOI), or when undercut exists, as the undercut diameter.
The shoulder fly (also known as a lateral raise) works the deltoid muscle of the shoulder. The movement starts with the arms straight, and the hands holding weights at the sides or in front of the body. Body is in a slight forward-leaning position with hips and knees bent a little.
