Beams Deflections (Method of Superposition)
wp.optics.arizona.eduStatically Indeterminate Beams The method of superposition is very useful for the reactions at the supports of statically indeterminate beams. As you may recall, a statically indeterminate beam is a beam with redundant supports (i.e. more supports than are required to maintain equilibrium of the beam).

courses.cit.cornell.eduConsideration of dynamic stability makes sense only for vehicles that are statically stable. But a vehicle can be statically stable and dynamically unstable (for example, if the initial tendency to return toward equilibrium leads to an overshoot, it is possible to have an oscillatory divergence of continuously increasing amplitude).

site.iugaza.edu.psTorsion on structural elements may be classified into two types; statically determinate, and statically indeterminate. In Figures 5.1.a through 5.1.e several examples of beams subjected to torsion are shown. In these figures, torsion results from either supporting a slab or a beam on one side only, or

Lecture 8: Energy Methods in Elasticity
ocw.mit.eduIn statically determined problems the bending moments can be expressed in terms of the prescribed line load or point load. In the latter case the M = M(P) and the total potential energy takes the form = U(P) Pw (8.21) The above representation will lead to the Castigliano theorem which will be covered later in this lecture.
