Redundant forces are chosen so that the structure is stable and statically determinate when you remove these forces. So, if you have two degrees of indeterminancy, you will have to remove two forces, remove three for three degrees, and so forth. Redundant forces are usually found when you have reaction forces AND a displacement, as it is obvious one caused the other. So when you remove these forces, the displacements are still there, and the structure has not changed, except that it is now statically determinant, and you can use method of superposition to figure out all your unknowns :)
What else can I help you with?
Explain statically indeterminate structure?
The structures which cannot be solved by the equilibrium equation are known as indeterminate structures.
What is the Mobility of a statically indeterminate structure?
mobility or DoF of a statically indeterminate structure is always less than zero and also we can have negative value of mobility. for checking this we have to see the Gruebler's criterion , wher D.F= 3(Movable link - 1) - 2*(number of Single D.F of kinematic pair) - ( number of two DF of kinetic pair) therefore, according to definition of satatically indeterminate structure have zero movable link . hence D.F will be either zero or negative.
What is the difference between a structure that is rigid and one that is flexible?
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
What does internal structure mean?
The Internal structure of a house is the arrangement of the various rooms,walls and ceilings while the internal structure of the human body is the patttern and position of the skeleton, muscles and organs. These contrast with the external structure - the outline or profile of the outside.
What kind of structure is the Eiffel Tower frame shell or mass?
eiffel tower is a frame structure.

Why use Statically indeterminate structures?
Statically indeterminate structures allow for more efficient use of materials and can accommodate larger loads compared to statically determinate structures. They also provide more stability and allow for more creative and innovative designs in engineering and architecture.
What is a redundant force?
redundant forces are the extra forces in a structure whose removal from a structure makes it statically determinate.for ex:in a structure of indeterminancy =2 ,2 forces can be removed

What is the difference between redundant and nonredundant structures?
A redundant structure has more structure than is absolutely necessary. This means that, if some part of the structure is damaged or removed, the structure will not necessarily fail or collapse, as another part can bear the load of the damaged or missing piece. A non redundant structure is dependent on every piece of the structure.
What is the best structure?
indeterminate structure
What is the best bridge structure?
indeterminate structure

When solving for truss forces why is it important to know that the structure is statically determinate?
it isn't at all!
What is the definition of the displacement method?
The displacement method is a technique used in structural engineering to calculate the deflections and internal forces in a structure by considering the displacements of the structure as a whole rather than analyzing individual components separately. It is commonly used in analyzing statically indeterminate structures and relies on the principle of virtual work.

What is tubular frame?
Space frame is a new type of roof truss load-bearing structure, and it is multiple statically indeterminate structure system. Space frame is a spatial structure connected by several pipe and node ball upon some regular pattern of geometric figure. It changes the ordinary frame structure of the general plane stress state, and it can bear the loads from all sides, even though the individual pipe in damage, it can automatically adjust the member forces, to maintain structural safety.Steel structure is classified by structural material; space frame is classified by the structural form.Space frame materials are steel, aluminum alloy, stainless steel, etc., in the practical use, steel is mainly used.
