Stress on 25 micron Fiber Under Elongation Load

In summary, the conversation is about determining the stress on a fiber subjected to an elongation load of 25 g. The participants discuss whether the stress is shear or tensile and how to calculate it using the formula F/A. The correct answer is found to be .125 MPa by not dividing the radius by 2 and then dividing by a factor of 1000. It is suggested that the text answer may be incorrect.

This doesn't seem particularly hard, thought it was simply an F/A situation but apparently not. A fiber with a diameter of 25 micro meters is subjected to elongation load of 25 g along the fiber axis. What is the stress on the fiber? Is the applied stress a shear or a tensiles stress. I said it was a tensil stress and went on to compute F/A. F was .025Kg * 9.8N and A was simply ((25*10^-6)/2)^2*pi. The resultant stress was 500 MPa. The correct answer is .125 MPa. Any suggestions??!

I get the same answer as you. Maybe the text answer is wrong?

yeah I'm going with text is wrong, .125 is found by not dividing the radius by 2 and then dividing by a factor of 1000...haha only thing I could find out, but thank you!
 

Related to Stress on 25 micron Fiber Under Elongation Load

1. What is the significance of studying stress on 25 micron fiber under elongation load?

The study of stress on 25 micron fiber under elongation load is important because it helps us understand how materials behave under different forces. This information can be useful in various industries, such as aerospace and engineering, where materials are subjected to high levels of stress and need to be able to withstand it without breaking.

2. How is stress defined in the context of this study?

In this study, stress is defined as the force per unit area that a material experiences when subjected to an applied load. It is measured in units of force divided by area, such as pounds per square inch (psi) or newtons per square meter (N/m²).

3. What factors can affect the stress on 25 micron fiber under elongation load?

The stress on 25 micron fiber under elongation load can be affected by various factors, including the type of material, the magnitude of the load, the rate of loading, the temperature, and the duration of the load. Other factors such as the presence of defects or impurities in the material can also affect the stress.

4. How is the stress on 25 micron fiber under elongation load measured?

The stress on 25 micron fiber under elongation load is typically measured using a universal testing machine, which applies an increasing load on the fiber until it breaks. The machine records the load and the corresponding elongation of the fiber, and the stress can be calculated by dividing the load by the cross-sectional area of the fiber.

5. What are some potential applications of the findings from this study?

The findings from this study on stress on 25 micron fiber under elongation load can have various applications. They can be used to improve the design and performance of materials in industries such as aerospace, automotive, and construction. The information can also be used in the development of new materials that can withstand high levels of stress, leading to more durable and efficient products.
