The only possible virtual displacement would be a displacement from the bead's position, formula_16 to a new position formula_20 (where formula_21 could be positive or negative).

It is the capability of the vacuum to permit the Electric field lines.

The ship was about 20 metres long and displaced between 60 and 100 tons.

The linear variable differential transformer (LVDT) (also called just a differential transformer, linear variable displacement transformer, or linear variable displacement transducer ) is a type of electrical transformer used for measuring linear displacement (position).

Greater regional cooperation is needed to prevent such displacement.

In 1998, the UN issued Guiding Principles on Internal Displacement, which sets out these legal rights.

In analytical mechanics the concept of a virtual displacement, related to the concept of virtual work, is meaningful only when discussing a physical system subject to constraints on its motion.

However sudden the initial displacement, the impact can last for generations, together with a long term need for clean water, shelter, health care, and other basic services, as victims of Hurricane Mitch in Central America in 1998 know from bitter experience.
