The electrostatic force per unit area
between two planar, semi-infinite surfaces separated by a distance D was approximated with an expression derived by Parsegian and Gingell (1972).
A scientist has proposed that the 101-story skyscraper may build stress, or force per unit area
, on underground faults.
Also, the ratio of stress expressed in either force per unit linear density or force per unit area
of original specimen and the strain expressed as either a fraction of the original length or percentage elongation.
possible to maximize the force per unit area
, the arrays are scaleable,
Ultimate tensile stress was calculated as force per unit area
in Megapascals (MPa), and percent elongation was calculated from measured extension.
