GEOG140 Chapter 3 (midterm 1) Civil Engineering 2024 New Review Earthquake - ANS-An episode of ground shaking caused by the sudden breaking of rock or by frictional sliding along a pre-existing fault in the Earth. Seismicity - ANS-Earthquake activity. Seismology - ANS-The scientific study of earthquakes. Seismic Waves - ANS-Vibrations generated by an earthquake that pass through the Earth or along its surface. Fault - ANS-A fracture on which one body of rock slides or slips past another...

Absorption When a wave transfers energy to the energy stores of a material. Acceleration A measure of how quickly velocity is changing. Accurate result A result that is very close to the true answer. Activity (radioactive) The number of nuclei of a sample that decay per second. Air resistance The frictional force caused by air on a moving object. Alpha decay A type of radioactive decay in which an alpha particle is given out from a decaying nucleus. ...

Which of the following is an internal reaction or resistance of tissue that is also known as deformation? 1. Mechanical Stress/Strain 2. Mechanical Failure 3. Load 4. Yield point - ANSWER-Mechanical Stress/Strain A tissue is said to be _______________ when it has greater or less strength depending on the direction of the load that is being applied. 1. Viscoelastic 2. Bending 3. Extensible 4. Anisotrophic - ANSWER-Anisotrophic Which of the following injuries is due to microtrauma or...

Stress - correct answer --Force per unit area that causes rocks to deform -units are Pascals -EX. confining and/or directed pressure Strain - correct answer -Amount of deformation expressed as a % of distortion Strength - correct answer --Rocks break when they fail, strength is exceeded -units are Pascals Why is knowing rock strength important? - correct answer --Design of tunnels, overpasses, roads, buildings -Integral for understanding how/where to drill, blast, design, construct ...

GLG 101 Final Exam | questions and answers | 2023/24 Rock Cycle - Magma cools and solidifies creating igneous rocks. Igneous rocks are exposed at the surface and eroded away creating sedimentary rocks. Sedimentary rock deform under heat and pressure to form Metamorphic rocks. How we determine the relative ages of rocks - We place rocks in their proper sequence of formation. Which rock formed first,second, third, and so on. Rock Types - Igneous Sedimentary Metamorphic Igneous Rock...

Intrinsic Injury - ANSWERSInfection (viral, bacterial) Extrinsic Injury - ANSWERSTissue stressed to the point of mechanical failure due to excessive force Primary Injury - ANSWERSDirect, immediate consequence of excessive force (trauma) ex. ACL tear, sprained ankle Secondary Injury - ANSWERSDelayed injury some time after initial trauma; an accomodation to an initial injury ex. sprained ankle causes knee or hip to hurt from gait compensation Acute Injury - ANSWERSMechanical failure ...

Dislocations - a defect in the crystalline lattice. Dislocations move within a structure when stress is applied Pinning - inhibits the dislocation from moving within the structure resulting in the metal becoming stronger and more brittle. Precipitates - small atoms that fit within the vacant spaces between base metal atoms Entanglements - grains of a structure becoming stretched out. Created by cold working Tensile strength - A measure of how much stress from pulling, or tension, a materia...

EASA ATPL | Limit Load Factor Limit Load Factor - correct answers The limit, up to which, deformations are elastic in nature Deformation that can be expected within 1.5x the limit load factor - correct answers Permanent deformation, not failure Ultimate Load Factor - correct answers Structural Failure Maneuvering Speed must ___ if the weight decreases - correct answers decrease 1) Limit Load 2) Ultimate Load 3) Safety Factor - correct answers 1) Max load anticipated in service 2)...
