Abstract
Temeljni zakon teorije elastičnosti poznat je pod nazivom Hookeov zakon. On glasi: „Vanjska sila koja djeluje na oprugu proporcionalna je njezinom produljenju“. Faktor proporcionalnosti je konstanta elastičnosti. U srednjoj školi radi se intuitivni izvod u kojemu se dolazi do zaključka da je konstanta elastičnosti ravne žice jednaka umnošku poprečnog presjeka opruge i Youngovog modula elastičnosti podijeljenog s početnom duljinom. Nadalje, uvriježeno je da se konstanta elastičnosti opruge također naziva konstanta elastičnosti. Takvim se pristupom pojavljuju poteškoće u razumijevanju, odnosno pojavljuje se miskoncepcija da se konstanta elastičnosti opruge može računati po formuli za konstantu elastičnosti ravne žice. Ovim radom za konstantu elastičnosti opruge uvodi se naziv efektivna konstanta elastičnosti. Time se rješava stvaranje potencijalne miskoncepcije, odnosno uvodi se razlika između naziva. Nadalje, u radu je grafičkom analizom pokazano da efektivna konstanta elastičnosti ovisi o gustoći namotaja opruge te površini koju zatvara jedan namotaj opruge. Ovaj rad ne uključuje analitičku analizu podataka.
Abstract (english)
The fundamental law of the theory of elasticity is known as Hooke's law. It reads: "The external force acting on the spring is proportional to its elongation". The proportionality factor is the elastic constant. In high school, an intuitive derivation is made, in which the conclusion is reached that the elastic constant of a straight wire is equal to the product of the cross section of the spring and the Young's modulus of elasticity divided by the initial length. Furthermore, it is common practice that the spring constant is also called the elastic constant. With such an approach, a misconception appears that the elastic constant of a spring can be calculated using the formula for the elastic constant of a straight wire. This work introduces the term effective elastic constant for the spring elastic constant. This solves the creation of a potential misconception, i.e. introduces a difference between the names. Furthermore, in the paper, it was shown by graphical analysis that the effective elastic constant depends on the density of the spring coil and the surface covered by one spring coil.
