Legend: The compressive force of the device (P) necessary to cause a deformation ”ƌ” is obtained by isolating ”P” in formula:\(P=\frac{4d\text{EBH}^{3}}{L^{3}}\), which ”E” is the modulus of elasticity, ”B” is the width of the spring, ”H” is the thickness of the spring and ”L” is its length. In order to obtain the value of the compression exerted by the system, the value of the compressive force (P) must be divided by the area of ​​the bulkhead (A).
