So 69 is correct.
Torque is a moment, a moment can be correctly expresseed as lb-ft in US customary units. Work in US customary units can be correctly expressed as ft-lb.
lb-ft are not the same units as ft-lb.
This is one more example of the screwed up US customary system of units resulting in people not understanding what they are doing. If people would use the correct US customary units for torque, lb-ft, then they would be less likely to make this common mistake.
If you think about it bit, it becomes obvious that work and torque are not interchangeable.
If you apply 100 lb-ft of torque to a lever and it dopesn't move, how much work have you done? You have dome zero work because there was no motion.
If you apply 100 lb ft of torque to a lever and rotate it through one full revolution, you have obviously done 628.32 ft lbs of work. Torque and work are not the same thing at all.
