What else can I help you with?
Where does the maximum bending moment occur in a simply supported beam?
It depends on the loading conditions of the beam, it will generally occur close to the middle of the span.
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 reverse bending?
When a cantilever beam is continuously loaded and released from mean position, in one direction only, it is called unidirectional bending, but when it is loaded alternately, first in one direction and then in the opposite direction from mean position, then it is called reversed bending.
What is ultimate bending strength?
It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.
Which one have more deflection hollow beam or solid beam?
solid beam have more deflection
Difference between unsymmetrical and symmetrical bending?
Symmetrical bending occurs when a beam is loaded uniformly along its length, resulting in bending stresses that are equal on both sides of the beam's neutral axis. Unsymmetrical bending occurs when a beam is loaded unevenly, causing different magnitudes of bending stress on opposite sides of the beam's neutral axis.
What kind of stresses are produced in a beam during transverse vibration?
If you load it normal to the beam axis you get bending stresses ( tension and compression) and shear stresses. If you load it along the axis you get axial stress ( tension or compression)
A bent rod to resist shear and diagonal stresses in a concrete beam is called?
STIRRUPS
What are the Bending moment diagram for simply supported beam loaded in its center?
zero
What has the author D M Macdonald written?
D. M. Macdonald has written: 'Loaded key reactions and stresses'
Where does the maximum bending moment occur in a simply supported beam?
It depends on the loading conditions of the beam, it will generally occur close to the middle of the span.
Effective length of a beam?
the efffective length of a beam is the length along the beam at which the beam will fail when a load is acting upon it. This effective length is usually near the centre of the beam as that is where the stresses are the greatest. For example a fat chick jumping up and down on the beam would reduce the effective length dramatically as the loads are semi-constant but ginormous.
What is example of transverse shear?
One example of transverse shear is when a beam is loaded vertically, causing shear forces to act horizontally across the beam's cross-section. This can lead to the beam experiencing bending and deformation.
What is the bending equation?
The bending equation, also known as the Euler-Bernoulli beam equation, describes the behavior of a beam under bending loads. It relates the bending moment, beam material properties, beam geometry, and load distribution to the beam deflection. The equation is typically solved to determine the deflected shape of a loaded beam.
What is the advantage and disadvantages of fixed beams?

What kind of stress occurs at a converging boundary?
Compressional stresses occur at convergent plate boundaries.
How does the relative important of bending and shearing stresses vary with the loading position of the beam?
i need the answer too..plesase anyone help me with that..now,asap
