Mechanical analysis of a simple object

Click For Summary
The discussion centers on analyzing the mechanical properties of a simple object, specifically a spring in mechanical pens. Participants suggest that the analysis can be expanded by introducing additional elements, such as damping or multiple masses connected by springs. The original poster expresses difficulty in starting the analysis and emphasizes the need for a practical object rather than a theoretical setup. They seek guidance on calculations and potential mechanical failures related to their chosen object. Overall, the conversation focuses on how to approach the mechanical analysis of everyday items.

The Attempt at a Solution


I really have no idea how to even start this but I thought of doing the spring in mechanical pens. I would appreciate any help :)

Yes, why not?
If you find it too easy, you can dampen the system and/or you can make the system more complicated by a setup:

Fixed point
|
spring
|
mass 1
|
another spring
|
mass 2

Thanks for the reply! The thing is that it needs to be an object that we use and I can't make a system up. I don't know how to go about the calculation, analysis of the mechanical setup as a whole and possible failures and concerns.
 
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?
