would you answer 100_lbs ? Yeah, you probably would. -LOL
But would you show your work...
SGAl = 2.6,
Suspension Force = 100-(100/2.6)= 61.54_lbf
Buoyancy Force = 100/2.6 = 38.46_lbf
Total Force = Buoyancy Force + Suspension Force = 100_lbf
Or would you leave those details of the answer hanging until your teacher marked "100_lbf" wrong? Not that I would ever do anything like that.  |
Thanks island and others!
What would be the result if you used seawater at SG of 1.022 for buoyancy force rather than freshwater at 1.00? If it makes no difference, that's the answer.
I don't think the depth makes any difference except for gravity and didn't mean to go down that black hole. I should have omitted the word "weight" from my original question and rephrased it as island did above.
