Diver trim

Index Diver trim

The stability and static trim of a scuba diver affect the convenience and safety of the diver both at the surface and under water during the dive. [1]

10 relations: Buoyancy, Buoyancy compensator (diving), Center of mass, Centroid, Diving cylinder, Diving weighting system, Metacentric height, Scuba diving, Surface-supplied diving, Torque.

Buoyancy

In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.

Buoyancy compensator (diving)

A buoyancy compensator, also called a buoyancy control device, BC, BCD, stabilizer, stabilisor, stab jacket, wing or ABLJ depending on design, is a piece of diving equipment with an inflatable bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed.

Center of mass

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.

Centroid

In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean position of all the points in the shape.

Diving cylinder

A diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set.

Diving weighting system

Divers wear weighting systems, weight belts or weights to counteract the buoyancy of other diving equipment, such as diving suits and aluminium diving cylinders.

Metacentric height

The metacentric height (GM) is a measurement of the initial static stability of a floating body.

Scuba diving

Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater.

Surface-supplied diving

Surface-supplied diving is diving using equipment supplied with breathing gas using a diver's umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell.

Torque

Torque, moment, or moment of force is rotational force.
