A). Use thermal expansion or compression;
B). If already in use, use several materials with different coefficients of thermal expansion.
C). General formula: A change of potential changes parameters of the system so that it produces an action or a flow.
The opposite:
A). A flow into a system changes its potential. Use it to affect other systems. (Potential is the moving force of actions)
Examples:
1. Temperature (it is a potential) changes the size of a metal part (it is the flow of length and deformation);
2. Water fills the barrel (this is a flow) and, as a result, water pressure is changing (this is a potential).
This is the Method 36 [37] | Index
