Homework Help Overview

The problem involves determining the height of the lowest point of a hanging cable, expressed in terms of specific constants related to the model. The context suggests a focus on the mathematical representation of the cable's shape.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the interpretation of the question, particularly the phrase "expressed in terms of the constants." There is an attempt to clarify that the lowest point occurs at x = 0, leading to questions about the height at that point.

Discussion Status

Some participants have offered interpretations and potential expressions for the height of the lowest point, while others are still seeking clarity on the wording of the question. There is no explicit consensus, but a direction towards understanding the constants involved has been noted.

Contextual Notes

Participants are grappling with the specific wording of the problem and the implications of expressing the height in terms of constants P, g, and H. The original poster's confusion about the question's requirements is acknowledged.

Homework Statement



"Expressed in terms of the constants in this model, how high is the lowest point of the cable?
(Assume the correct dimension to be in metres)"

Homework Equations



Equation for the shape of a hanging cable.

edit: P, g & H are constants.

The Attempt at a Solution


The lowest point is of course at x = 0.
I'm confused by "Expressed in terms of the constants in this model"

the question asks not where the cable is its lowest, but what is height of its lowest point.
 
Yeah so y(0) is the height of the lowest point?
In the OP is said the lowest point is at x = 0, I'm Having trouble understanding the wording of the question.

I think the answer is Height = H/Pg, since cosh(0) = 1. But I'm not sure if that's "In terms of the constants"
 
ya, that is right
