Nodal Mass Units
Question:
Hello,
I''m doing a dynamic analysis and am trying to figure out how to enter Nodal masses.
My model is in units of kN and m. If I have a mass of 10,000 kg to add to a node, how would I convert that into kN/g?
Thanks,
Answer:Hi,
The mass [weight * (time2/length)] is the weight divided by the acceleration of gravity.
[mass = weight / g (accelerationofgravity)]
10,000kg = 10,000kgf/g(m/s2) = 98(kN) / 9.8(m/s2) = 10 kN/g
So, enter 10 for nodal mass value.
Thank you.
