Hi All,
Im using a stepper motor to pull down essentially a heavy box (~60lbs) that has rocking legs. The box is rests on a base. The stepper motor will be rigidly attached to the base or the ground. Im trying to figure out how much torque the stepper motor needs to be rated for, before...
Im looking for a comprehensive list of thermal air properties. I'm used to using ones in the back of textbooks that have values every 25C or so, and extrapolating in between. Does anyone know if a more thorough/comprehensive list is available for free?
