Concentric and eccentric contractions of the obliques, back extensors and erector spinae cause the trunk to rotate. The latissimus dorsi, anterior deltoid, subscapularis, biceps and pectoralis major all contract concentrically during the acceleration phase to bring the racket to the ball for contact.

Shim a Concentric Chuck. Here is a quick way to offset–just shim a concentric chuck such as a 3-jaw, a 6-jaw, or a 4-jaw with scroll. Simply insert a shim under one of the jaws to shift the work off center by that precise amount. This idea came from Shred who used it to make some offset clamps for his mill.

A pipe reducer reduces the pipe’s diameter. In pipes, there are two types of reducers: concentric and eccentric. Concentric Pipe Reducer or Conical Reducer. The center of both ends of a concentric reducer, also known as a conical reducer, is on the same axis. It maintains the pipeline’s centerline elevation.

Eccentric action. Opposite to concentric action, eccentric action involves the muscle lengthening whilst it is under tension. The origin and the insertion move further away from each other. Eccentric actions are used when muscles have to slow down body parts and control movements.

Concentric exercise describes the shortening of a strength training movement, while an eccentric movement is the lengthening portion of the movement. Think of a basic bicep curl. The lifting portion of the curl is the concentric movement and the lowering of the curl is the eccentric movement. Pretty straightforward.

Eccentric turning, also known as offset turning, is a type of lathe operation. It is typically used to machine parts with features that are not concentric to the spindle axis, such as the eccentric drive of a steam engine and a crankshaft. The main difference between turning and eccentric turning is the center of rotation of the workpiece.
