What is meant by 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.
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. If the number of unknowns exceeds the number of equations, the structure is statically indeterminate. Otherwise, it is statically determinate.
What does determinate mean?
Definition of determinate 1 : having defined limits a determinate period of time. 2 : definitely settled a determinate order of precedence. 3 : conclusively determined : definitive a determinate answer.
What is determinate structure 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.
Why is M 2j 3?
In a simple truss, m = 2j – 3 where m is the total number of members and j is the number of joints. A simple truss is constructed by successively adding two members and one connection to the basic triangular truss. In a simple truss, m = 2j – 3 where m is the total number of members and j is the number of joints.
How do you know if something is static determinate?
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.
How do you determine if a structure is determinate or indeterminate?
Determinate structures are analyzed just by the use of basic equilibrium equations. By this analysis, the unknown reactions are found for the further determination of stresses. Redundant or indeterminate structures are not capable of being analyzed by mere use of basic equilibrium equations.
What is determinate plant?
Determinate and Indeterminate Determinate varieties (including bush varieties) reach a certain plant height and then stop growing. The majority of their fruit matures within a month or two and appears at the ends of the branches.
