Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
Hydrostatics, also known as fluid statics, is the study of fluids at rest (i.e. in static equilibrium). The characteristic of any fluid at rest is that the force exerted on any particle of the fluid is the same at all points at the same depth (or altitude) within the fluid.
In structural engineering, the direct stiffness method, also known as the matrix stiffness method, is a structural analysis technique particularly suited for computer-automated analysis of complex structures including the statically indeterminate type.
These characteristics are also known as I–V curves, referring to the standard symbols for current and voltage. In electronic components with more than two terminals, such as vacuum tubes and transistors , the current–voltage relationship at one pair of terminals may depend on the current or voltage on a third terminal.
This characteristic is important in determining whether an aircraft pilot will be able to control the aircraft in the pitching plane without requiring excessive attention or excessive strength. [ 1 ] The longitudinal stability of an aircraft, also called pitch stability, [ 2 ] refers to the aircraft's stability in its plane of symmetry [ 2 ...
Static Enthalpy: −∞ P a: ρ a: C u (upstream velocity) h ou: h u +∞ P a: ρ a: C s (slipstream velocity) h od: h d: Relationship Equal Equal Unequal Unequal Equal Comments Pressure will be atmospheric at both −∞ and +∞ Density will be equal at both −∞ and +∞ Velocity will change due to flow across an assumed converging duct
A beam deforms and stresses develop inside it when a transverse load is applied on it. In the quasi-static case, the amount of bending deflection and the stresses that develop are assumed not to change over time. In a horizontal beam supported at the ends and loaded downwards in the middle, the material at the over-side of the beam is ...
Characteristics are also a powerful tool for gaining qualitative insight into a PDE. One can use the crossings of the characteristics to find shock waves for potential flow in a compressible fluid. Intuitively, we can think of each characteristic line implying a solution to along itself. Thus, when two characteristics cross, the function ...
