> [@bob\_2](#): > > Of course the Newton is better "_the amount of energy needed to accelerate 1 kilogram of mass at the rate of 1 metre per second squared"_. That should be, “the amount of _force_ needed…” The amount of energy needed will depend upon the duration of time that you accelerate the mass. ---

As promised, here are the pics: [http://picturetrail.com/sfx/album/view/24389868](http://picturetrail.com/sfx/album/view/24389868) One more question relative to above-referenced formulas. Would they be appropriate for the steam turbines? ---

Would they be appropriate for the steam turbines? The equation is valid for _any_ rotating machinery that produces or absorbs torque: measure the torque, measure the RPM, you can calculate power output (or absorption). ---

I spent a entire happy day touring the Midway and also didn’t have enough time to see everything I wanted to or talk the ears off of all the interesting volunteers. ---
