Rate of change of area with deformation

Click For Summary
SUMMARY

The discussion focuses on the mathematical analysis of the rate of change of area with deformation, specifically in the context of stretching a wire. Participants emphasize the importance of clear parameterization of variables and the necessity for high-quality images to accurately convey the problem. A discrepancy is noted between the problem statement, which indicates stretching, and the solution suggesting a decrease in a variable over time. This highlights the need for precise definitions and clarity in problem-solving approaches.

PREREQUISITES
  • Understanding of basic calculus concepts, particularly derivatives.
  • Familiarity with geometric properties of shapes, specifically area calculations.
  • Knowledge of material deformation principles in physics.
  • Ability to interpret and analyze graphical representations of mathematical problems.
NEXT STEPS
  • Research the mathematical principles of deformation and strain in materials.
  • Explore the concept of parameterization in mathematical modeling.
  • Learn about the relationship between area and deformation in geometric contexts.
  • Investigate best practices for presenting mathematical problems visually, including image quality and clarity.
USEFUL FOR

Students and professionals in mathematics, physics, and engineering who are dealing with deformation problems, as well as educators looking to improve their problem presentation techniques.

Homework Statement
Suppose I had a coil as shown in the picture. If I was to stretch the wire in the x-axis at a rate v. What is the area as a function of time.
Relevant Equations
X^2+Y^2=z^2
241230
241231
Could I please get a hint on how I should start this question/how I should parameterize these variables?
I'm going to head to sleep as I am from the eastern time zone. I apologize ahead of time for my delayed reply.

The image you posted was very poor quality, with bad lighting. Please post a clearer image of your work.

Or, preferably, type it out.
 
You will also have to describe better the situation you are considering. In the problem statement, you say you stretch the wire, but in your solution you say that y decreases with time.
