Want to anneal two aluminum samples at home with household equipment as a little experiment. Just wondering what you guys think on the methods. Not sure if I am better off setting the oven to maximum heat or using the fireplace. Just going to quench in water.

Shigley's Engineering Design is great

Ok thank you! I have managed to use the same method as btrueblood but have been getting the result Torque=2/3*F*mu*R where mu is the coefficient of friction. And for best wrench yes i am looking into how much the normal force needs to be. The head is going to be interchangable so the floor can...

I have been trying to solve for an equation that describes the torque created on a shaft as a result of friction between a mophead in rotating in contact with a hospital floor. Both coefficient of frictions are known, along with rotation speed(which as far as i gather is irrelevant) the diameter...
