Record number: 1, Textual support number: 1 CONT
An isostatic structure must have the appropriate number of members in accordance with Mobius' law. If a structural member or restraint ... is added, it becomes a hyperstatic structure. 1, record 1, English, - isostatic%20structure

(...) structure [dont] les sollicitations(effort normal, effort tranchant, moment fléchissant) relatives à une section quelconque peuvent être déterminées à partir des seules équations de la statique.(Dans le cas contraire, la structure est dite "hyperstatique".) 3, record 1, French, - structure%20isostatique
Record number: 1, Textual support number: 2 DEF
Ensemble des liaisons internes ou externes d’une structure assurant son indéformabilité géométrique sous l'effet des forces extérieures(...) Lorsque les liaisons sont surabondantes, le système est dit "hyperstatique" et nécessite la prise en considération des déformations pour le calcul des efforts. 4, record 1, French, - structure%20isostatique

Member in a frame or truss that may be omitted in the structure without affecting the ability to analyse the frame or truss by ordinary static methods (such as a counter-diagonal in a truss). 4, record 2, English, - redundant%20member
Record number: 2, Textual support number: 1 CONT
Redundant members may be used for the purpose of producing a more rigid structure than that which would be obtained with just enough to satisfy the conditions for static equilibrium. 5, record 2, English, - redundant%20member
Record number: 2, Textual support number: 2 CONT
A hyperstatic structure has more members or restraints than are required by Mobius' law, and those in excess of static requirements are called "redundancies". If the redundancies are removed, the structure becomes isostatic. 3, record 2, English, - redundant%20member

Lorsque les liaisons sont limitées à celles strictement indispensables pour assurer l'indéformabilité géométrique de la structure, on a un système isostatique. Dans une structure hyperstatique, on peut donc supprimer les liaisons surabondantes sans que l'indéformabilité géométrique soit mise en cause. 1, record 2, French, - liaison%20surabondante
Record number: 2, Textual support number: 2 CONT
Si les pièces utilisées sont trop longues pour ne pas fléchir sous leur propre poids, ou pour ne pas flamber quand elles travaillent par compression, on les rigidifie au moyen de pièces secondaires. Ce sont des barres surabondantes mais auxquelles on ne donne que juste les sections nécessaires à remplir leur rôle de soutien. 2, record 2, French, - liaison%20surabondante

In a structure of the type of a truss, ... the condition in which there are more members than would be needed to produce stability if the joints are considered to be pin-connected. 2, record 3, English, - redundancy
Record number: 3, Textual support number: 1 CONT
The degree of redundancy or indeterminacy ... of a structure is a number which represents the difference between the number of unknown conditions which must be satisfied and the number of equations of static equilibrium which are applicable. 2, record 3, English, - redundancy
Record number: 3, Textual support number: 2 CONT
A structure with redundancies is "hyperstatic", one without redundancies is "isostatic". 3, record 3, English, - redundancy

hyperstatique : Se dit d’un système de corps ayant entre eux plus de liaisons qu’il peut en exister entre solides indéformables. (La détermination de l’équilibre d’un tel système nécessite de faire intervenir les déformations élastiques de chaque corps.) 1, record 3, French, - hyperstaticit%C3%A9
