Two springs have spring stiffness of 1.6 IN/m
and 2 KN/m respectively. If they are connected
in parallel, what will be the spring stiffness?
Answers
Answer:
ExplaIn lower segment/zone, two springs, each of constant k, are in parallel.
∴ Equivalent spring constant =(k+k)=2k
Now, for the system, there is a spring (of constant 2k) in upper segment and a spring (of constant 2k) in lower segment.
They are in series
∴k
r
=
(k
