87Vector area — In geometry, for a finite planar surface of scalar area S, the vector area :mathbf{S} is defined as a vector whose magnitude is S and whose direction is perpendicular to the plane, as determined by the right hand rule on the rim (moving one s… …
88Persistence length — The persistence length is a basic mechanical property quantifying the stiffness of a long polymer.Informally, for pieces of the polymer that are shorter than the persistence length, the molecule behaves rather like a flexible elastic rod, while… …
89Weight machine — A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance, and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines… …
