High school student here I am designing an experiment to test the effect of temperature on the torque required to twist a peice of metal, and need some advice on where to start researching. What I need help with is A) finding a table of the torque required to twist steel when cold, and B) finding some equation/principle/law that relates the temperature of the metal to the torque required to turn it. Answers to questions that will probably be asked: 1. I plan to use mild steel, probably annealed if I can get it 2. I can go very high heat wise, and plan to use a laser thermometer to measure the temperature of the metal 3. I will be using a setup that uses weights to produce torque, and that isolates the motion to only rotational (as opposed to bending downwards) 4. Im open to any neccessary/beneficial changes to the experiment, any and all advice is greatly appreciated. 5. I don't have an endless money tree so any reccomendations of buying some huge expensive torsion testing machine will be fruitless. 6. I probably have screwed up some of the terminology, sorry in advance, tell me if I did.
