These results indicate that changes in the material composition and design of lacrosse sticks are changing the timing and rate at which balls release from the crosse pocket.
But it is typical of that time, when there were changes in the way people played, and changes in the material.
They undergo tremendous shearing and gravitational forces that can cause them to fracture into smaller pieces or melt, causing chemical changes in the material and loss of water or other volatile compounds.
3. Create an illustrated timeline that documents the development of either the tennis racket or a string instrument, focusing on changes in the material and design of the strings.
Any changes in the material and/or geometric properties of these structures are considered as damage.
As that spot starts to heat up, changes in the material cause that spot to soak up even more energy.
Obtaied results enable identification of the laser induced changes in the material.
It takes into account the sensitivity of the method to changes in the material and associates measurement uncertainties.
Still, little is known concerning which pathways may be directly involved in cell response to changes in the material surface.
This nonconservative energy will be involved in micro-structural changes in the material before being dissipated as thermal energy.
Substantial changes in the material structure and progressive increases in film thickness were observed with increasing applied power.
