Click For Summary
A 30 m aluminum bar with a diameter of 50 mm is under a tensile stress of 172 MPa, and the task is to determine its final diameter using Young's modulus of 69,116 MPa and a Poisson's ratio of 0.4. The discussion addresses the appropriate forum for posting such questions, clarifying that the original poster may have intended to seek assistance rather than present a challenge. The thread was moved to a more suitable forum for help. The focus remains on calculating the final diameter based on the given parameters.

A 30 m long aluminum bar having a diameter of 50 mm is subjected to a tensile stress of 172 MPa. Find the final diameter of the aluminum bar if E=69116MPa and Poisson's ratio=0.4?

Hi Joe_1234,

I saw you posted your question in the "Problem of the Week" forum, but I am sorry, that forum is meant ONLY for directors to post a problem on weekly basic. Do you mean to provide a challenge problem for our members to attempt at a solution, or do you mean to ask for help there?

As a temporary measure, I have moved your thread to other forum, assuming you wanted to get some help to answer the problem. :)
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
