Question on elementary statics multiple choice

Click For Summary
The discussion centers on a homework problem involving the calculation of torques in elementary statics. The user derived the equation for tension (T) as [mgL]/[(L-x) * sin(theta)], which does not match any provided answer options. They express confusion about the discrepancy and suggest that answer option 4 might contain a typo, potentially aligning with their calculation. The user seeks clarification on their approach and the accuracy of the answer choices. The thread highlights common frustrations with unclear test questions in statics.

Homework Equations


sum of torques = 0

The Attempt at a Solution


So I tried to put the torques into the equation:

Sum torques = mgL - T *sin(theta) * (L-x) = 0.

Solving for the T gave me [mgL]/[ (L-x) * sin(theta) ]. This is not an option in the answers.
Could anyone please help me out in understanding where I possibly derailed, and why the authors think the answer is 4. Thanks in advance!

What if answer 4) has a typo, and it should read: ##\frac{mgL}{(L-x)sin\, \theta}## ?

If yes, then that is the answer. The test questions are written by some crummy authors [thanks a lot whoever you are!]
 
Thanks for the help!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
