If you can solve the beam reactions by the equations of equilibrium, then it is statically deterrminate.
If not, that is, more unknown reactions than the equations of equilibrium, then it is indeterminate, and you need to know something about its deformation to solve the reactions.

What is propped simply supported beam?
A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A propped cantilever beam is a beam which is fixed at one end ( no translation or rotation) and simply supported ( no translation) at the other end. A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A simply supported beam is a beam which is simply supported at both ends. A propped simply supported beam is a beam which is simply supported at both ends and simply supported at some other point such as at the center, to reduce deflection under load. Propped beams are statically indeterminate.
Which one have more deflection hollow beam or solid beam?
solid beam have more deflection
Why does a longer beam length mean greater deflection?
Deflection of beam depends upon load and length of beam. Larger the beam, larger will be it's selfweight
What is the advantage and disadvantages of fixed beams?
There isn't really an advantage of having a fixed beam vs. a simply supported beam, it depends on what application the beam is for. If one of the design criteria of the beam is that it be able to deflect from one end to another then you are going to want to use a fixed beam. For example such applications could include a diving bored. A simply supported beam differs from a fixed beam because the beam is supported at both ends. Thus when a simply supported beam is loaded, the deflection will occur throughout the beam, since the ends are confined and will remain as they were. Furthermore on a fixed beam, (the end that is fixed) will have restrictive forces and moments keeping the end from moving.
What is a deflection in cantilever beam?
it will depend upon the load and moment applied on the beam.
Why use Statically indeterminate structures?
What are indeterminate structure
Explain statically indeterminate structure?
The structures which cannot be solved by the equilibrium equation are known as indeterminate structures.
Is continuous beam an determinate or indeterminate?
If a continuous beam rests on 3 or more supports it is indeterminate
What are advantages of statically indeterminate structures in construction?
they can redistribute the load and have greater moment capacity
What is propped simply supported beam?
A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A propped cantilever beam is a beam which is fixed at one end ( no translation or rotation) and simply supported ( no translation) at the other end. A cantilever beam is a beam which is fixed at one end ( no translation or rotation). A simply supported beam is a beam which is simply supported at both ends. A propped simply supported beam is a beam which is simply supported at both ends and simply supported at some other point such as at the center, to reduce deflection under load. Propped beams are statically indeterminate.
What has the author Clarence W Hudson written?
Clarence W. Hudson has written: 'Deflections and statically indeterminate stresses' -- subject(s): Strains and stresses
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.
Difference between determinate and indeterminate structures?
determinate structures are analysed by using equation of equilibrium or statics ie.., EV=0,EH=O,EM=0. EXAMPLE: simply supported beam ,cantilever beam,single or double over hanging beam. indeterminate beams are not capable of being analysed by using equation of statics. along with equation of statics we need some conditions for finding the unknowns. Example : fixed beam, propped cantilever beam, and continuous beam
How do you determine redundant forces in a statically indeterminate structure?
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 :)
How can you tell when an object has been statically charged?
I you touch it, and it shocks you, then it was statically charged.
Why infinity infinity is not indeterminate form?
It IS indeterminate.
What is the difference between statically determinate and indeterminate beam?
Determinate structures are analysed 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 analysed by mere use of basic equilibrium equations. Along with the basic equilibrium equations, some extra conditions are required to be used like compatibility conditions of deformations etc to get the unknown reactions for drawing bending moment and shear force diagrams.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.
