מאמר על ה- קפיצים בטור ובמקביל
1. קפיצים בטור
אם הקפיץ מחובר בטור, כמו באיור בצד, אז:
1. הגדלת אורך הקפיץ = הגדלת אורך 1 + הגדלת אורך 2
Δy = Δy1 + Δy1
2. הכוח שחווה קפיץ שווה ערך = הכוח שחווה קפיץ 1 = הכוח שחווה קפיץ 2
Fs =F1 =F2
3. The equivalent spring’s constant (ks)
1 / ks = 1/k1 + 1/k2
בעיה לדוגמה 1:
Two identical springs each have a constant of 100 N / m connected in series. If the spring’s arrangement is given a load so that it increases 4 cm in length, then the increase in the length of each spring is …
פתרון:
The total increase in the length of the two springs is 4 cm, therefore the increase in the length of each spring is 2 cm.
2. Springs in parallel
If the spring is connected in parallel, as in the figure on the side, then:
1. The increase in the length of the equivalent spring = the increase in the length of spring 1 = the increase in the length of spring 2
Δy = Δy1 + Δy1
2. The force experienced by the equivalent spring = the force that is experienced by spring 1 + the force experienced by spring 2
Fs =F1 + ו2
3. The equivalent spring’s constant (kp)
kp = k1 + k2
בעיה לדוגמה 2:
Two springs each with constant c arranged in parallel. The אביב קבוע of this arrangement becomes …
פתרון:
The equivalent spring’s constant (kp) = c + c = 2c
