A B
12800[---------------------------------------------- --------]12800 up 1″
lbs. 161″ lbs.
Both A and B weight is 12800 lbs.
Arm between A and B is 161″
If B is elevated 1″, what will be resulting weight of A and B?
Just some food for thought...
To answer this question wouldn't it refer to how much the weight changes over the arm after B is elevated one inch?
Yes, your version of the question is correct. Sorry for any confuseion.
