Hi all,
I do not know if I'm in the right place to ask this question ..? I am on a small project concerning a machine to sight the firearms and this machine will be provided with a shock absorber as well as a spring in compression in order to absorb the recoil of the weapon. I do not have the training to calculate the strength of the damper and the spring in question, so I need help for that. Here's my question, if a rifle has a recoil force of 30 foot pounds (41 NM) and an acceleration of 15 feet (4.5 meters second) what damper force will stop the recoil of the weapon in a 3-inch stroke (75mm) long or what spring force will do the same job? I include 2 links, one for the table where I took my data and the other showing the type of damper I will use, they are available in various lengths and forces. The strength of the dampers are given only in Newton and not in Newton / meter, I understand that either the damper or the spring will have the same forces but I am confused with the conversion of Newton only and / or the Newton / meter or the ft / lbs. Could someone help me or tell me where I can find help on this? Thank you for your attention!
