The stiffness of one short spring is 13500 N/m
<em><u>Solution:</u></em>
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
<em><u>The stiffness of one spring in series is given as:</u></em>

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
