What happens when identical springs are connected in series?
The same load acts on every spring.
- Each spring experiences the same tension T.
- Each spring extends by x.
- Total extension =
n × x .
For two springs in series: Total extension = 2x.
The extensions add together, making the system easier to stretch.
Exam tip: Don’t confuse series with parallel. In series, extensions add. In parallel, the load is shared. Mixing them up is a common exam trap!
AHA! More springs, more extension. Not by sight, but by INSIGHT!
