Equation for combined strings force constant

Click For Summary
SUMMARY

The discussion focuses on deriving the equation for the total force constant (KTOTAL) when two strings with individual force constants K1 and K2 are connected in series. The key insight is that the tension remains constant across both strings, leading to the relationship KTOTAL = (K1 * K2) / (K1 + K2). This formula allows for the calculation of the combined force constant when the two strings are hooked together, simplifying the analysis of their mechanical properties.

PREREQUISITES

Hi,
you have two strings, one has force constant K1, the other Force Constant K2.
You hook the two strings together.


I need to see a derived euqation using K1 and K2 to find KTOTAL (the force constant when he two strings are placed together).


Please keep things as simple as possible :D thx

Figure it out for yourself! Hint: If the two strings are in series, the tension in each must be equal.
