## How do you calculate static determinate?

A truss is considered statically determinate if all of its support reactions and member forces can be calculated using only the equations of static equilibrium. For a planar truss to be statically determinate, the number of members plus the number of support reactions must not exceed the number of joints times 2.

### What is statistically determinate beam explain with example?

Example of determinate structures are : simply supported beams, cantilever beams, single and double overhanging beams, three hinged arches, etc. Redundant or indeterminate structures are not capable of being analysed by mere use of basic equilibrium equations.

**What is the formula for statically indeterminate?**

Σ MA = 0: Fv ⋅ a − VB ⋅ (a + b) − VC ⋅ (a + b + c) = 0. Since there are four unknown forces (or variables) (VA, VB, VC and HA) but only three equilibrium equations, this system of simultaneous equations does not have a unique solution. The structure is therefore classified as statically indeterminate.

**What is a statically determinate structure?**

A statically determinate structure is one that is stable and all unknown reactive forces can be determined from the equations of equilibrium alone. A statically indeterminate structure is one that is stable but contains more unknown forces than available equations of equilibrium.

## What is kinematically determinate structure?

A kinematically determinate structure can be defined as a structure where, if it is possible to find nodal displacements compatible with member extensions, those nodal displacements are unique.

### What are the different types of statically determinate structures?

Example of determinate structures are: simply supported beams, cantilever beams, single and double overhanging beams, three hinged arches, etc. Examples of indeterminate structures are: fixed beams, continuous beams, fixed arches, two hinged arches, portals, multistoried frames, etc.

**What do you mean by statically determinate beam?**

In regards to beams, if the reaction forces can be calculated using equilibrium equations alone, they are statically determinate. On the other hand, if the reaction force can’t be determined using equilibrium equations only, other methods have to be used, and the structure is said to be statically indeterminate.

**Is fixed beam statically indeterminate?**

For a general system of loading, a fixed beam is statically indeterminate to third degree. For vertical loading, a fixed beam is statically indeterminate to second degree.

## Is the structure statically determinate or indeterminate?

### What is SI of fixed beam?

If we consider a fixed-fixed beam, its KI=0 as we know that all deflections on both the ends are zero and there is no unknown deflection in this case. (It has SI=3.)

**Which one of the following is statically determinate beam?**

2. Which of the following is statically determinate structure? Explanation: Double overhanging can be analysed by available three equilibrium equations i.e. ∑Fx=0, ∑Fy=0, and ∑M = 0. Explanation: This is case of vertical loading only.

**Which is statically determinate beam?**

## Why are beams 1 and 2 statically determinate?

In the figure above, the beams number 1 and 2 are statically determinate structures due to the following reasons: 1- Beam number 1: the number of unknown forces is 3 = the number of equations is 3. 2- Beam number 2: the number of unknown forces is 3 = the number of equations is 3.

### When is the structure of an equation statically determinate?

For each case, a mathematical equation is formed. If the number of equations = the number of unknowns, then the structure is statically determinate. If, on the other hand, number of equations < the number of unknowns, the structure is statically indeterminate, and hence, other methods need to be used to analyze it.

**What is the formula for 2-beam number 2?**

2- Beam number 2: the number of unknown forces is 3 = the number of equations is 3. Provided that the force exerted on the above beam is equal to 100 kN located at exactly the middle of the 3 m beam. We need to evaluate the reactions of the support.

**What is the equation for three dimensional statics?**

In three dimensional statics, the summation of forces in x, y and z directions, and the summation of moments in x, y and z directions all must equal zero. For each case, a mathematical equation is formed.
