Have You Calculated the Maximum Bending Moment Yet?

Click For Summary
The discussion centers on calculating the maximum bending moment in structural engineering. Participants inquire about the progress made by ashish181 and request details on any schematics created, including force magnitudes and directions. Understanding these elements is crucial for accurately determining the bending moment. The conversation emphasizes the importance of clear visual representations in structural analysis. Overall, effective communication of forces is essential for successful calculations.

Welcome, ashish181!

What work have you done so far?
Any schematic with magnitudes and directions of forces as described in the problem?
 
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?
