Tolerancing Q: Virtual Condition & MMC Explained

  • Thread starter Thread starter theone

Click For Summary
The discussion focuses on understanding the concepts of virtual condition and maximum material condition (MMC) in tolerancing. The original poster seeks clarification on how to apply these concepts to a specific problem, indicating that existing resources are insufficient. A response suggests that the solution can be approached through basic arithmetic by determining the maximum and minimum values for a specified dimension. The goal is to ensure that the clearance gap remains within defined limits despite variations in the clevis dimension. Clear comprehension of these tolerancing principles is essential for accurate engineering applications.

The Attempt at a Solution


I read about the virtual condition http://www.symphonytech.com/articles/GDT_Design.htm
but I don't really understand the approach used to solve the problem and was wondering if someone could explain the solution. where does the MMC come into the the solution?

That article is not very helpful .

Your problem can be solved with simple arithmetic .

Just see if you can work out the maximum and minimum possible values of dimension C so that the clearance gap always stays within stated limits for any variation of the clevis dimension .
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
