A light spring which has a force constant of 8N/m is cut into two equal parts . What is the force constant for each part ??
isnt that each part has a force constant of 8N/m ??
that means if you apply N of force, the spring stretches m
cut the spring in half ... attach them with a light non-stretchable string.
apply a force of 8N. Each piece stretches m
the force in each spring "piece" is 8N
for two springs in series, the effective force constant of a single spring equivalent to the two is
