WebDeterminate vs. Indeterminate. A static system is determinate if it is possible to find the unknown reactions using the methods of statics, that is, by using equilibrium equations, otherwise it is indeterminate. 🔗 Web13 SOLUTION Externally stable, since the reactions are not concurrent or parallel.Since b = 19, r = 3, j = 11, then b + r = 2j or 22 = 22. Therefore, the truss is statically determinate. By inspection the truss is internally stable. Externally stable.Since b = 15, r = 4, j = 9, then b + r > 2j or 19 > 18. The truss is statically indeterminate to the first degree.By inspection the …
WebIn the case of a Statically Determinate structure, we then just apply equilibrium For the Statically Indeterminate case, this is more involved:--> Approach 1. Apply equilibrium 2. Determine relations between forces and Displacements (use of constitutive relations) 3. Enforce Compatibility of Displacements Result: Several simultaneous equations. WebTo determine whether a structure is externally determinate, the following equations are used: (1) Statically unstable externally: r < 3 + e c (2) Statically determinate externally: r = 3 + e c (3) Statically …
Webstatically determinate structure. All the remaining forces can be determined using the equations of equilibrium. 2. Force Method for Beams – One Redundant Force • Check for indeterminacy: # of unknowns > # of equations. (3m + r) > (3j + c); m = # of members, r = # of reactions, j = # of joints, c = # of internal hinges. WebStatically Determinate Structure If the structure can be analyzed by use of the equation of equilibrium is known as statically determinate structure. The equation of equilibrium are, Sum of horizontal force is zero, Sum of …
WebAug 1, 2024 · The number of reactions in excess of the number of equilibrium equations is called the degree of statical indeterminacy. Any reaction in excess of that which can be obtained by statics alone is said to be redundant. Thus, the number of redundants is the same as the degree of indeterminacy.
