stress design
101solids, mechanics of — ▪ physics Introduction science concerned with the stressing (stress), deformation (deformation and flow), and failure of solid materials and structures. What, then, is a solid? Any material, fluid or solid, can support normal forces.… …
102Antioxidant — Model of the antioxidant metabolite glutathione. The yellow sphere is the redox active sulfur atom that provides antioxidant activity, while the red, blue, white, and dark grey spheres represent oxygen, nitrogen, hydrogen, and carbon atoms,… …
103Nuclear meltdown — Three of the reactors at Fukushima I overheated, causing core meltdowns. This was compounded by hydrogen gas explosions and the venting of contaminated steam which released large amounts of radioactive material into the air.[1] …
104Beam (structure) — A statically determinate beam, bending (sagging) under an evenly distributed load. A beam is a horizontal structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the… …
105Occupational safety and health — is a cross disciplinary area concerned with protecting the safety, health and welfare of people engaged in work or employment. The goal of all occupational safety and health programs is to foster a safe work environment.[1] As a secondary effect …
106Tension member — Tension members are structural elements that are subjected to axial tensile forces. They are usually used in different types of structures. Examples of tension members are: bracing for buildings and bridges, truss members, and cables in suspended …
107Properties of concrete — Concrete has relatively high compressive strength, but significantly lower tensile strength, and as such is usually reinforced with materials that are strong in tension (often steel). The elasticity of concrete is relatively constant at low… …
108Discovery and development of cyclooxygenase 2 inhibitors — Cyclooxygenases are enzymes that take part in a complex biosynthetic cascade that results in the conversion of polyunsaturated fatty acids to prostaglandins and thromboxane(s).[1] Their main role is to catalyze the transformation of arachidonic… …
109Operation Sandblast — Part of Cold War (1953–1962) …
110Concrete — This article is about the construction material. For other uses, see Concrete (disambiguation). Outer view of the Roman Pantheon, still the largest unreinforced solid concrete dome.[1] …
