Does anyone know if the Gage Block physics is now understood?
Gage Block Physics: Is It Understood?

In summary, the conversation discusses the understanding of Gage Block physics and a suggestion to summarize a related video. One person questions if it's worth watching the video and another suggests conducting experiments to test the hypothesis of Van der Waals forces.

Why don't you summarize the video?
If it's not worth your time to summarize it, why is it worth my time to watch it?

Go to your local glass store and buy half a dozen pieces of 1/8 inch thick window glass cut into 3x4 inch pieces. Use fine sandpaper to dull the sharp edges. Clean very well. Press and twist them together, they should stick. Similar physics? Glass microscope slides also can be stuck together. Looked at carefully you should see interference fringes. Wet one with water and press and stick together, they seem to stick together better. As you slide the glass past each other notice the change in friction as you increase the force pressing them together, it does not seem to be linear.

Really excellent, Stevie. Many thanks. An incentive to learn more about Van der Waals and to calculate the holding force.
1. What are gage blocks and how do they work?
Gage blocks are precision measuring tools used in industrial settings for calibrating and verifying the accuracy of other measuring instruments. They are typically made of high-grade steel and have extremely flat and parallel surfaces. The blocks are used by stacking them together in various combinations to create a specific length for measurement. The accuracy of gage blocks is based on the principle of wringing, where the molecular attraction between the blocks creates a strong bond, resulting in a precise measurement.
2. What is the principle behind the accuracy of gage blocks?
The accuracy of gage blocks is based on the principle of wringing, which is the molecular attraction between two surfaces. When two gage blocks are placed together, the molecules on the surfaces create a bond, making it difficult to separate them. This bond ensures that the blocks maintain a precise distance between them, resulting in accurate measurements.
3. How are gage blocks calibrated and verified for accuracy?
Gage blocks are calibrated and verified using a precision measuring instrument, such as a coordinate measuring machine (CMM). The CMM measures the distance between the gage blocks and compares it to the known standard. If the measurement is within the acceptable tolerance, the gage blocks are considered accurate. They may also be verified using an optical flat and monochromatic light source, which allows for the detection of any imperfections or defects in the blocks.
4. What are the factors that can affect the accuracy of gage blocks?
The accuracy of gage blocks can be affected by various factors, such as temperature, humidity, and wear and tear. Temperature changes can cause the blocks to expand or contract, affecting their dimensions. Humidity can also cause the blocks to rust, which can alter their dimensions. Wear and tear from frequent use can also affect the accuracy of the blocks, making regular calibration and maintenance necessary.
5. Are there different types of gage blocks for different applications?
Yes, there are different types of gage blocks for different applications. Standard gage blocks are used for general purpose measurements, while rectangular gage blocks are used for specific measurements, such as angles and height. There are also square, round, and thread gage blocks for more specialized applications. It is important to use the correct type of gage block for the specific measurement to ensure accuracy.
