Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
The word architrave is also used to refer more generally to a style of mouldings (or other elements) framing the top of a door, window or other rectangular opening, where the horizontal "head" casing extends across the tops of the vertical side casings where the elements join (creating a butt joint, as opposed to a miter joint).

The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
2. A measure of the internal forces acting within a deformable body. 3. A quantitative measure of the average force per unit area of a surface within a body on which internal forces act. stress–strain curve string duality string theory structural load subatomic particle Any particle that is smaller than an atom. sublimation
The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...
The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength.
For perfectly brittle materials, yield strength and ultimate strength are the same, because they do not experience detectable plastic deformation. The opposite of brittleness is ductility . The toughness of a material is the maximum amount of energy it can absorb before fracturing, which is different from the amount of force that can be applied.
In 1901, the 3rd General Conference on Weights and Measures (CGPM) established this as their official definition of weight: The word weight denotes a quantity of the same nature [Note 1] as a force: the weight of a body is the product of its mass and the acceleration due to gravity.
