I just thought about the strength of springs, and during my research, I found that springs(obviously) lose strength when compressed for a long time, but I have read that springs can also "rest". Could someone explain this to me? I thought that even a momentary compression of a spring would decrease its strength. Or is it that a certain amount of time is needed until the spring starts losing strength?
