If a chain of 30 identical short springs linked end-to-end has a stiffness of 450 n/m, what is the stiffness of one short spring?

The stiffness of one short spring is 13500 N/m

Solution:

We are given a chain with number of spring N = 30 and linked end to end ( in series) and stiffness of this chain is 450 N/m

We have to find the stiffness of one short spring

The springs are identical, which means they have same stiffness

The stiffness of one spring in series is given as:

Where,

N is the number of springs

is the stiffness of one spring

is the stiffness of this chain

Substituting,

Therefore,

Thus the stiffness of one short spring is 13500 N/m
