Examples of concentric phenomena

Concentric
Coaxial cable

Coaxial cable is a cable consisting of an inner conductor, surrounded by a tubular insulating layer typically made from a flexible material with a high dielectric constant, all of which is then surrounded by another conductive layer , and then finally covered again with a thin insulating layer on the outside....
 cable
Cable

A cable is a large fiber or metal rope, used for hauling, lifting, or towing, or an assembly of two or more insulated electrical conductors, laid up together as an assembly....
 is a cable type used in TN-C-S earthing systems where the combined neutral and earth core completely surrounds the live core(s). This minimises the risk of completely cutting through the combined neutral and earth without first completely cutting through the live cores.

Concentric muscles contractions
Muscle contraction

Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may #Eccentric contraction, #Concentric contraction or #Isometric contraction....
 are those in which the muscle shortens.
