I need to find what spring will balance an arm at 45 degrees(adsbygoogle = window.adsbygoogle || []).push({});

the arm is 5m and can be considered as a UDL of 1.6kg/m

the situation is that the arm starts upwards at 90 degrees and as it goes down it puts tension on the extension spring

5*1.6 = 8kN

acting 2.5m along the beam

which is 1.77m in direction x (horizontal)

8000*1.77 = 14160Nm (the moment acting at 45degrees)

how do I find the details on the spring? (diameter, length etc)

Maybe i'm approaching it wrong, any advice would be appreciated :)
