Is anyone familiar with the behavior of a material under torsion?

I have a laboratory report due tomorrow morning, and I've been trying to figure out how I'm supposed to calculate the plastic torque, so I can get the yield torque, of two different members under torsion. I have a series of data points that I can reference, as well as a graph. There must be an engineer familiar with this stuff on this board!

oh fuck, it doesn't matter. If they've put it in a prac lesson, then the answers are all in the assigned material. If you can't find them, you're not looking hard enough. This is not the 'do my homewoek' forum.

University level. But I wasn't going to ask for help with my homework as much as I was asking for clarification about a the way a particular property interacts with another property, as it is not covered in my lecture notes/textbook/can't find it on the internuts. Never fear, I'm sure I'll be able to get along without it!

I know all about members under torsion!

Unfortunately I'm a physicist, not an engineer, but I would gather from the name that plastic torque is where you've applied enough torque that it begins to deform permenantly(so if you let go it wouldn't return to its original shape)

Ya, I figured everything out. I didn't need to know it anyway, but I was getting frustrated earlier this morning, and I was trying to figure out a bunch of data that wasn't asked for in the paper. Like the modulus of toughness.

Also, converting from degrees to radians is super handy. Took me an hour and a half before I figured out that I should do that. =p
