Don't know how if the rule meter will be titled or not

    Meter
Click For Summary
The discussion revolves around the confusion regarding the positioning of a meter rule in a physics problem. Participants clarify that the rule should be tilted and placed on a bench rather than directly over a pivot. They emphasize the importance of marking specific measurements, such as 49.7 and 84.2, on the diagram. One user expresses uncertainty about using a template but is encouraged to attempt drawing the diagram for feedback. Overall, the conversation highlights the need for clarity in interpreting instructions and accurately representing measurements in diagrams.

Hi Syndy,

Could you use the template again next time ?

it says that to draw the rule tilted and in bench and to use suitable number of weight
Strange, I read "Draw on Fig. 5.1 the metre rule with load Q on it".
All they want you to do is let the correct end of the ruler rest on the bench and write some numbers in relevant places. I would just copy the 49.7 and 84.2 -- after all they mention a "49.7" mark and a "84.2 mark"

I'm pretty much forbidden by PF rules to show you the picture I just had fun making, but if you can post an attempt, I'm certainly allowed to comment :wink: !

Thank you very much for your reply.
Do you mean I don't put the meter rule over the pivot instead I put it on bench? The answer says the rule to be rule tilted and on bench!

Do you think it will be like this?

Sorry I don't know how to use the template.

Yes, that would be the diagram BvU has, I'm sure.

The marking notes in the 'solution' mention "suitable number(s)", but I suppose Syndy's diagram demonstrates that he/she correctly interpreted those numbers.

If you want to make absolutely sure, draw in both numbers.

Thank you very much for your help. I appreciate it.
 
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?
