what are the different mouse technique?
I had this same problem in a house once. I recall fixing it by putting a 9 volt battery in as a back up. You stated there is no battery back up. I am not sure if you mean you haven't put a battery in, or if you mean there is simply not a battery back up connection with your detector. It is possible that your detector is interlocked with other detectors in the house. That is the fire code in most places. If that is the case, perhaps there is a bad connection between the other detectors. And that is causing the chirp. That is probably a long shot though. Another possibility is that the detector is simply defective. Hope this was helpful somehow. Best regards.
I am a contractor that replaces/installs smoke detectors frequently. MANY hard wired smoke detectors do not have battery back up.
Just use conservation of energy. Pe 1/2 k x^2 also, your rubber bands with lengthen everytime you use them due to the hysteresis effect, which never allows them to return to their normal size again hooke's law would probably work too, but then mass would have little to do with ur load curve, you could substitute it into the conservation of energy equation but meh
its a sterile glove used by doctors, nurses and medical practionersduring operation!!!
Almost all hardwired smoke detectors have battery back-ups. You might want to look again. I change my batteries in my hardwire detectors once a year. They might have forgot to put the battery in for you.
