Çözüldü Work in "British Imperial Unit System" (Whatever the heck it is!)

If a cable that weighs 3 pounds per foot is used to lift 1000 pounds of iron ore up a mineshaft which is 300 feet deep, what is the work done?

pound = libra (lb)
Plural of foot: feet (ft)
gravity ≈ 32.7 ft / s^2
Work ≈ (1000 lb + 300 ft·3 lb / ft)·(32 ft / s^2)·300 ft ≈ 768636 newton·meters ≈ 768637 joules ≈ 768.6 kilojoules (kJ).
