# springs watch

1. sry, new problemo

"two identical springs 250mm of length are suspended vertically side-by-side from a fixed point. a 40n weight is attached to the ends of the two springs. the length of each spring is then 350mm. calculate the tension in each spring."

i put 40 newtons but apparently that's wrong--instead it's 20n? since the spring isn't accelerating doesn't that mean it has 0 net force on it??:

It's because there are two spings. Both the springs together are supplying a tension of 40n vertically upwards to remain in equilibrium. So each spring has a tension 20n. Because two springs on tension 20n will hold a weight of 40n
