Torque Problem Static equilibrium

Click For Summary
The discussion centers on solving a torque problem related to static equilibrium. The user initially calculates torque using an incorrect perpendicular distance from the pivot. It is clarified that the correct distance to use is the one from the point of force application to the pivot. The correct torque calculation requires this adjustment to accurately reflect the applied force's effect. Understanding the proper distance is crucial for solving the problem correctly.

How to do this question ??

The Attempt at a Solution



I know sum of torque and force = 0
at fapplied i got torque = 25sin(45) * 3.8m = 67.18N ..

But don't know what to do next !

All they asking for is the torque of the applied force about the pivot.

So your formula is correct however your value for the perpendicular distance is incorrect. You need to usethe distance from Fapplied to the pivot.
 
ohh crapp i have to use distance from pivot which is 3 right ??

Yes...You need to use distance between the pivot and application of force.
 
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?
