A Scientific response:
Yes a Newton is equal to 1 kilogram meter per second squared. Or Mass
multiplied with acceleration.
Since on earth, acceleration due to gravity, the only applicable a, is
9.8 meters per second squared.
Now 1 pound is defined as 4.448 Newtons. Therefore the D ring can hold a
total force of 25,000/4.448 = 5620 pounds. This D ring therefore will
hold, most likely, everybody with no problem, even when falling.
