Avibration absorber, which is a spring-mass system (k2, m2), is added to a system (k, mi) subject to a harmonic force f(t) = fo cos @t. (a) derive the amplitudes of steady-state response for mi and m2. (b) find the relation between k2 and m2 that leads to no steady state vibration of mi.

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?
