Hi there,
firstly I have to apologize if this is not the right section of the forum to post my question...
Well, what I need is a more sophisticated Newton meter, to measure the force on the line. Let me describe the whole thing: I am a paragliding pilot and we use gliders that have lots of lines which connect me and the canopy above my head. Well, every now and than tho whole glider has to be checked if it is still safe to fly with and part of that test is also to measure the force at which one of randomly selected line breaks. (that line is later replaced with a new one).
So I build a system where one end of the line is fixed to the wall and the other is fixed to the motor which moves at a constant speed away from the wall. Now to measure the maximum load before the line breaks I need a force gauge that will after the experiment is finished give me the information I need.
There is only one problem. Force meters are really cheap if you are looking at 5N of force, but as soon as the force gets larger, so does the price. For a brand new force gauge with maximum load of 1000 kg I would have to say goodbye to about 1000 eur.
So my question to all of you here is: Where could I possibly get a used (second hand) force gauge with maximum load of at least 360 kg that would tell me the maximum measured force during the experiment or show the graph on the computer?
I also thought about making a force meter like Newton did: using one strong spring, but this would look really unprofessional to the people that don't know physics - and I don't want to explain to each and every one the whole idea behind the spring.
Thanks for all the help!
