Torsion Bar
Torsion Bar
(OP)
I have a torsion bar we use in our product that now is 2"x2" with 3/16 wall in HSS, hollow tube.
We need to change this to 1.5"x3" with the same wall thickness. Everything else to remain the same.
Will this be a safe change from a torsional strenght point of view?
What chart figures could I check to ensure we are not making the product weaker?
Any expertise on this would be much appreciated.

Look at this site, although you will need to convert to metric you can compare the torsional constants J for both sections:-

all other things being equal, the new section has lower torsion stresses.
