1. The problem statement, all variables and given/known data All springs are the same. There's a horizontal Bar. 1 spring is attached to the top of the bar on the left most side. Then a distance "a" from that is a 2nd spring attached to the bottom of the bar. Then the same distance "a" from that is a 3rd spring attached to the top of the bar. A force P is applied down a distance "a" from the 3rd spring. Is this a series or parallel system? 2. Relevant equations 3. The attempt at a solution Even though all springs are attached to the bar, won't their displacements be different because they are different distances from P? And so the springs are in series. is this correct? Thanks for any help.
