General relationship for springs connected in series
1. Let 2 bodies connected with inextensible string.
If 1st body is pulled by a force and remained at rest, EQUAL force also exerted on 2nd object.
Thus spring#1 and spring#2 extended with equal force, x1 and x2
2. Total extension is x1+x2 due to F.
Subt. (1) in (2)
Keff =k1k2/k1+k2 like resistors in parallel
