Question

A spring of length 3L & spring constant k is cut into 2 parts of length L & 2L what is the ratio of spring constant of two parts?​

Answer 1

Answer:

its easy

Explanation:

Considering the spring to be ideal of length L, if it is cut into 1:2 ratio, the spring constant will get changed to 3k and 1.5k(3k/2) for L/3 and 2L/3 part of it, respectively.

Spring constant is not a universal constant. It depends on spring diameter, no. of windings and elastic modulus. Reducing the length of a spring reduces the number of windings on which spring constant is inversely dependent. Thus, it increases the spring constant for a spring having smaller length (small number of windings).
