|
Deformation |
Change in shape due to the application of force |
|
|
Drag force |
Found to be proportional to the square of the speed of the object; mathematically: Fd=.5CpAv^2, where C is the drag coefficient, A is the area of the object facing the fluid, and p is the density of fluid |
|
|
Friction |
A force that opposes relative motion or attempts at motion between systems in contact |
|
|
Hooke's law |
Proportional relationships between the force F on a material and the deformation 🔺️L (the triangle is delta) it causes, F = k🔺️L |
|
|
Kinetic friction |
A force that opposes the motion of two systems that are in contact and moving relative to one another |
|
|
Magnitude of kinetic friction |
Fk=mewk×N Where mewk is the coefficient of kinetic friction |
|
|
Magnitude of static friction |
Fs<mews×N, where mews if the coefficient of static friction and N is the magnitude of the normal force |
|
|
Shear deformation |
Deformation perpendicular to the original length of an object |
|
|
Static friction |
A force that opposes the motion of two systems that are in contact and are not moving relative to one another |
|
|
Stoke's law |
Fs=6×pi×r×n×v, where r is the radius of the object, n is the viscosity of the fluid, and v is the objects velocity |
|
|
Strain |
Ratio of change in length to original length |
|
|
Stress |
Ratio of force to an area |
|
|
Tensile strength |
Measure of deformation for a given tension or compression |
