3. Board Design
When designing the board, keep in mind that the amount of strain which occurs will increase
  depending on the sizeand material of the board.
Relationship with amount of strain to the board thickness, length, width, etc.]

Relationship between load and strain
When the load is constant, the following relationship can be established.
· As the distance between the supporting points (L) increases,the amount of
strain also increases.
→Reduce the distance between the supporting points.
· As the elastic modulus (E) decreases, the amount of strain increases.
→Increase the elastic modulus.
· As the board width (w) decreases, the amount of strain increases.
→Increase the width of the board.
· As the board thickness (h) decreases, the amount of strain increases.
→Increase the thickness of the board.
Since the board thickness is squared, the effect on the amount of strain becomes even greater.
