What is the total moment when the empty-weight moment is 885,957 in-lb and the added water/hydraulic moments total 4,003 in-lb?

• A. 885,957
• B. 890,000
• C. 888,000
• D. 889,960

Answer: (D)

To get the total moment, you add the moments together. The empty-weight moment is 885,957 in-lb and the added water/hydraulic moments total 4,003 in-lb. Adding them gives 885,957 + 4,003 = 889,960 in-lb. So the total moment is 889,960 in-lb. The other figures would occur if you didn’t include the added moments or if you rounded differently, but the exact sum is 889,960 in-lb.
