Optical glass is usually free of strain, but when mechanical or thermal stress is exerted upon it, glass shows birefringence. Stress F (Pa), optical path difference (nm) and thickness of glass d (cm) have the following relationship:
In this case, proportional constant is called the photoelastic constant. It is listed in this catalogue at a unit of (nm/cm/105 Pa). The photoelastic constant is the material constant that will change by glass type. By using it, optical path difference can be computed from given stress. Internal stress can also be computed from optical path difference.
Photoelastic materials are transparent materials that change their optical properties when subjected to mechanical stress. When stress is applied, these materials exhibit a birefringence effect, which causes them to change colors or patterns under polarized light. They are commonly used in stress analysis and to visualize stress distributions in mechanical components.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
No. The definition of acceleration is change in velocity.
i believe that the definition of a constant multiplier is when you are obviously multiplying thing more than once
the definition is when individuals in a reproduce at a constant rate
Bahnzeitkonstante
Unmoving, resolute, unchanging
It is motion in a straight line at a constant velocity.
A number without a variable. Ex.) 5 is a constant, 5x is not.
erosion
The state of being in proportion.

The thing that never changes
Not sure about a defention, but the definition is something which does not change.
One definition of the derivative is: "Rate of change". Since a constant is constant, it doesn't change, and the rate at which it changes is zero.
