| strength-duration curve | A graph relating the intensity of an electrical stimulus to the length of time it must flow to be effective. See: chronaxie, rheobase. (05 Mar 2000) |
| ionic strength | Symbolised as g/2 or I and set equal to 0.5σmizi2, where mi equals the molar concentration and zi the charge of each ion present in solution; if molar concentrations (ci) are used instead of molality (and the solution is dilute), then I == 0.5(1/ρo)σcizi2 where ρo is the density of the solvent; a number of biochemically important events (e.g., protein solubility and rates of enzyme action) vary with the ionic strength of a solution.

| tensile strength | The maximum stress a material subjected to a stretching load can withstand without tearing. (12 Dec 1998) |
| yield strength | The amount of stress at which a permanent (plastic) deformation in a component becomes measurable (usually taken as 0.2% permanent strain). (05 Mar 2000) |
| ultimate strength | The maximum stress achieved prior to failure of a component on a single application of the load. (05 Mar 2000) |
| fatigue strength | The stress level below which a particular component will survive an indefinite number of load cycles (typically about 50% of the ultimate strength of the component). (05 Mar 2000) |
