hi, i am back, i just opened the trhead: https://www.physicsforums.com/threads/seismic-isolator-based-on-magnetic-forces.872369/ tell me if that vacation travel goes around :D

Hi, i am an student of civil engineering and i am doing my graduate thesis. so sorry if i misspell, english is not my native languaje. so, here we go :D Homework Statement Before entering in details you (whoever you are) most know: The system is scaled for obvious reasons. The system consists...

i think answering you question goes against the introduction myself thread rules :v, anyway it is a engeenering topic with very specific physics topics (seismic isolator with restoring magnetic force). I am making the thread lucking for luck if anybody could help.

hi, thanks for replying. right now is quite a good moment to visit my conuntry, exchange rate can make it happen cheap. your guess was right i am a undergraduate student in the last period of the career, which is thesis :v
