## How do you find the degree of statical indeterminacy?

For a given structure the degree of static indeterminacy is unique but different sets of static unknowns can be selected as redundant forces, as we will see later on in the document. To obtain the degree of static indeterminacy we compare the number of static unknowns with the number of equilibrium equations.

**How do you find the degree of indeterminacy of structure?**

A degree of static indeterminacy n can be calculated from a number of equilibrium equations E and a number of unknown forces N on a structure by the equation: (8.1) therefore structures can be classified as: n = 0 statically determinate structures.

### How do you find the degree of kinematic indeterminacy?

We obtain the degree of kinematic indeterminacy (DKI) by deducting from the kinematic capacity of the structure (KC), the number of conditions of dependence (∑CD). Both expressions, (6) and (7), can be used to determine the degree of kinematic indeterminacy.

**What is degree of redundancy?**

The degree of indeterminacy or redundancy is given by the number of extra or redundant reactions to be determined. The beam shown in figure 3 (a) is statically indeterminate to one degree because there are three unknown reactions and statics has only two reactions.

#### What is the degree of indeterminacy of fixed H?

Explanation: It is indeterminate to 2 degrees.

**What is the degree of indeterminacy of a fixed arch?**

indeterminate to 3 degrees

What is the degree of indeterminacy of a fixed arch? Explanation: It is indeterminate to 3 degrees.

## How do you calculate static and kinematic indeterminacy?

Degree of Static Indeterminacy of Pin Jointed Plane Frame ( Plane Truss )

- m = 2(j-3) + 3.
- or, m = 2j – 6 + 3.
- or, m = 2j – 3.
- where,
- m = number of members.
- j = number of joints.
