Definitions An “abnormal ground condition” is any casual water, ground under repair or hole, cast or runway on the course made by a burrowing animal, a reptile or a bird. Addressing the Ball A player has addressed the ball when he has grounded his club immediately in front of or immediately behind the ball, whether or not he has taken his stance.

Human Physiology/Print Version What is Ground Effect? The principle of Wing-in-ground-effect or (W.I.G) has been known for a long time. Ground effect is a natural phenomenon, as an aerofoil approaches the ground its lifting ability increases and the drag reduces. The lift to drag ratio increases as the pattern of circulation around the wing changes. This pattern of air around the wing causes a cushion on the underside to develop.

- COMPRESSIBILITY AND SETTLEMENT. 9.1 COMPRESSIBILITY OF AN ELASTIC SOLID. Structures such as buildings, bridges, etc. are frequently erected on soil as the founding. material. Since soil is a compressible material these structures experience downward movement. or settlement. Depending on the soil and the size of the structure these settlements may vary from.

Deformation of Rocks Stress is a force applied over an area. One type of stress that we are all used to is a uniform stress, called pressure. A uniform stress is where the forces act equally from all directions. In the Earth the pressure due to the weight of overlying rocks is a uniform stress and is referred to as confining stress.hen a rock is subjected to increasing stress it changes its shape, size or volume. Such a change in shape, size or volume is referred to as strain. When stress is applied to rock, the rock passes through 3 successive stages of deformation.

Seismic Design Principles In order to characterize or measure the effect of an earthquake on the ground (a.k.a. ground motion), the following definitions are commonly used: 1  Acceleration is the rate of change of speed, measured in gs at 980 cm/sec² or 1.00 g. For example, 0.001g or 1 cm/sec2 is perceptible by people.

Deformation (mechanics) Deformation (mechanics) Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body. A deformation may be caused by external loads, body forces, or changes in temperature, moisture content, or chemical reactions, etc. Strain is a description of deformation in terms of relative displacement of particles in the body that excludes rigid-body motions. Different equivalent choices

- In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.trictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity.

- The isochoric deformation gradient is defined as, resulting in the isochoric deformation gradient having a determinant of 1, in other words it is volume stretch free. Using this one can subsequently define the isochoric left Cauchy–Green deformation tensor tensor.or isotropic hyperelastic materials, the Cauchy stress can be expressed in terms of the invariants of the left Cauchy–Green deformation tensor (or right Cauchy–Green deformation tensor).

Definition of 'creep' As the stress continues, the extension of the metal caused by creep eventually leads to failure.During creep, damage accumulates in the form of internal cavities.Creep is the tendency of a solid material to move or change shape slightly as a result of stress that continues for some time.

- of the ground at a volcano is one of the oldest methods for monitoring deformation caused by moving magma. When magma forces the ground up, the slope of adjacent areas will usually tilt away from the center of uplift by only a fraction of a degree. Conversely, if the ground subsides as a consequence of magma moving below, the slope of adjacent areas will tilt toward the center of subsidence. We use electronic tiltmeters for continuously recording such ground tilts on volcanoes, and they have become the most widely used instrument for measuring volcano ground deformation in real time.

Soil compaction In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densification as air is displaced from the pores between the soil grains.ut clays which do not crack as they dry cannot recover from compaction on their own unless they host ground-dwelling animals such as earthworms — the Cecil soil series is an example.

The cyclic behaviour of soils and effects of geotechnical factors in microzonation During earthquakes, soil layers are subjected to multi-directional cyclic stresses with different amplitudes and frequencies that lead to cyclic deformations and to changes in stress–strain and strength properties of soil layers.

Ground (electricity) In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.or measurement purposes, the Earth serves as a (reasonably) constant potential reference against which other potentials can be measured. An electrical ground system should have an appropriate current-carrying capability to serve as an adequate zero-voltage reference level.

Deformation (engineering) This type of deformation is also irreversible. A break occurs after the material has reached the end of the elastic, and then plastic, deformation ranges. At this point forces accumulate until they are sufficient to cause a fracture. All materials will eventually fracture, if sufficient forces are applied.
