An appology? You jest! As I said, I have not found the relevent paper, I am in job transition and it's packed away. I will freepmail you when I do.
BTW you DID see the dictionary definition of "horsepower" didn't you? 33,000 pounds is a wee bit more than the 1,000 that you said would collapse anything short of an elephant, isn't it?
I wonder how much a knight in shining armor, with his arms, and the saddle, and the armor for the horse weights? Anyone?
