Homework Help Overview

The discussion revolves around a center of mass problem related to a sculpture, where participants are evaluating the most likely choice for the center of mass based on given options. There is a focus on the y-component of the sculpture's mass and its implications for the center of mass location.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants express confusion regarding the provided options for the center of mass, questioning the appropriateness of the suggested answers based on their understanding of mass distribution. There are attempts to model the problem physically and considerations of the question's clarity.

Discussion Status

The discussion is active, with multiple participants sharing their perspectives on the validity of the options presented. There is a general sentiment of skepticism regarding the question's construction and the proposed answers, but no consensus has been reached on a definitive answer.

Contextual Notes

Participants note that the question may be poorly constructed, leading to confusion about the expected location of the center of mass. There is also mention of the possibility of using a physical model to explore the problem further.

Homework Statement



See the attachment below. The solution is stated to be number 4 (option a). I am having trouble understanding this. It seems that a majority of the sculpture's mass (in terms of its y-component) is well below the vertical component of point 4, and hence should lower the CM from where 4 is. I know the question asks for the "most likely" choice, but 3 seems more appropriate, no?

I agree. It's a very bad question. None of those points are anywhere near where I would expect the CoM.

You can prove the point by making a model out of card.
 
Can't possibly be "4" for the reason you state. I'm not convinced 2 or 3 is right either as too much area above those points.
 
I'd put it about half way between 3 and 4. Very sloppily constructed question.
