p c is the pressure at the centroid of the vertical projection of the submerged surface; A is the area of the same vertical projection of the surface; ρ is the density of the fluid; g is the acceleration due to gravity; V is the volume of fluid directly above the curved surface
An example of lateral earth pressure overturning a retaining wall. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and ...
The main loads for which an arch dam is designed are: [1] [12] Dead load; Hydrostatic load generated by the reservoir and the tailwater; Temperature load; Earthquake load; Other miscellaneous loads that affect a dam include: ice and silt loads, and uplift pressure. [1] [12] The Idukki Dam in Kerala, India.
Rankine's theory (maximum-normal stress theory), developed in 1857 by William John Macquorn Rankine, [1] is a stress field solution that predicts active and passive earth pressure.
In continuum mechanics, hydrostatic stress, also known as isotropic stress or volumetric stress, [1] is a component of stress which contains uniaxial stresses, but not shear stresses. [2] A specialized case of hydrostatic stress contains isotropic compressive stress, which changes only in volume, but not in shape. [ 1 ]
Center of pressure is used in sailboat design to represent the position on a sail where the aerodynamic force is concentrated.. The relationship of the aerodynamic center of pressure on the sails to the hydrodynamic center of pressure (referred to as the center of lateral resistance) on the hull determines the behavior of the boat in the wind.

The vector T may be regarded as the sum of two components: the normal stress (compression or tension) perpendicular to the surface, and the shear stress that is parallel to the surface. If the normal unit vector n of the surface (pointing from Q towards P) is assumed fixed, the normal component can be expressed by a single number, the dot ...
