The bending moments introduced in tension members can reduce their load-carrying capacity by causing buckling or lateral-torsional instability. These moments can also lead to premature failure due to the combined effects of bending and axial tension stressing the material. It's important to consider these effects when designing tension members to ensure structural safety and integrity.
Bending is another common stress that materials experience, in addition to tension, compression, and torsion. When a material undergoes bending, one part of it is in tension while the other part is in compression due to the applied load or moment.
It is neither; a push is compression and a pull tension; in bending one surface stretches in tension and the other surface is in compression, and the n middle does nothing. There are four things you can do to an object; push or pull, bend, shear, and twist
The five forces that occur in structures are compression (pushing together), tension (pulling apart), bending (combination of compression and tension), shear (sliding forces acting parallel to each other), and torsion (twisting forces). These forces need to be considered in the design and analysis of structures to ensure their stability and safety.
To determine compression and tension in trusses, you can analyze the forces acting on the members using the method of joints or method of sections. By calculating the forces in each member, you can identify which members are in compression (pushing) and which are in tension (pulling).
Flexural compression refers to the type of stress that occurs in a beam or structural member when it is subjected to a bending load. This compression stress acts on the upper portion of the beam, while tension occurs on the lower portion. It is important to consider both compression and tension when designing structural elements to ensure they can withstand bending loads.
A positive bending beam experiences convex deformation on the top side and concave deformation on the bottom side when subjected to bending moments, typically indicating tension at the bottom and compression at the top. In contrast, a negative bending beam shows the opposite behavior, with the top side experiencing concave deformation and the bottom side convex, leading to compression at the bottom and tension at the top. Understanding these bending states is crucial for structural analysis and design to ensure safety and integrity.
Positive and Negative are just directions. The main concern is whether there exist a bending moment or not. Then according to sign convention we classify bending moment as positive or negative. Elaborating on this point, If clockwise bending moments are taken as negative, then a negative bending moment within an element will cause "sagging", and a positive moment will cause "hogging" Sagging and hogging moments are important to differentiate. As hogging causes tension in the upper part of the beam x-section whereas sagging causes tension in the lower part of the x-section. This concept is of great importance in designing reinforced concrete members as we have to provide steel rebar in the zone of beam having tensile stress as concrete is weak in tension.
In a truss analysis, only the axial loading on each member is of interest. Since the pinned joint cannot transmit a bending moment, no bending stress is transmitted to the individual members, and thus only axial (tension or compression) loading occurs in the truss members.
When a simply supported beam is subject to bending; the top of the beam will be subject to compression, and the bottom of the beam will be subject to tension (think about the bottom of the beam stretching as it bends i.e. tension). Concrete is strong in compression but weak in tension, so steel reinforcement is added to allow it to resist this tension and carry bending sufficiently. Note: bars are generally added to the compression side too but that's for another day.
Bending is another common stress that materials experience, in addition to tension, compression, and torsion. When a material undergoes bending, one part of it is in tension while the other part is in compression due to the applied load or moment.

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)
Compression members (vertical elements in structures) Slight imperfections in tension members and beams.

Gas bottles are cylindrical or spherical because circular hoops can withstand internal pressure by pure tension in the tank material instead of bending. Materials can take more force in tension than in bending.
