Reaching for the Gold: Analyzing Forces to Snap a Pipe in Half

In summary, the conversation is about trying to find out the maximum forces required to snap a pipe in half due to torsion. The specific pipe being discussed is a 3"OD mechanical round tube with 1/4" wall and a length of 20ft, with a 14" long arm welded to one end and a 3000psi cylinder pushing or pulling the arm. The pipe was supported at both ends and the middle, but still snapped in half. The participants are interested in seeing the work and asking for the equation for maximum torsion on a cylinder.

I’ll try for the gold ring first and then come back to earth.
Trying to find out the max forces to snap a pipe in-half (torsion problem)
I have a 3”OD mechanical round tube with 1/4” wall its (ASTM-A 519) grade and 20ft long. At one end is welded a 14” long arm with a 3000psi cylinder(column load of 125000lb.) pushing or pulling the arm. It was supported in three basic areas, at both ends and the middle. Its snapped in-half.
What forces had to act on the far end to snap it? Very interested in seeing the work, Show work.

We're also very interested in seeing the work. Your work. See the sticky thread "FAQ: Why hasn't anybody answered my question?"

I would be glad to show you the work, so, considering neither one of us have a degree yet let's start with an equation-- Do you know what the equation is for max. torsion on a cylinder??

Thank you

So much for the gold ring!
 

1. What is the purpose of "Reaching for the Gold: Analyzing Forces to Snap a Pipe in Half"?

The purpose of this experiment is to understand the concept of forces and their effects on objects. By analyzing the forces acting on a pipe, we can determine the amount of force required to snap it in half.

2. How is the experiment conducted?

The experiment involves setting up a pipe on a flat surface and attaching a force gauge to one end. The other end of the pipe is then pulled down until it snaps. The force gauge measures the amount of force required to snap the pipe.

3. What types of forces are involved in this experiment?

There are two main forces involved in this experiment: tension and compression. Tension is the force that is pulling the pipe apart, while compression is the force that is pushing the pipe together.

4. What factors can affect the amount of force required to snap the pipe?

The amount of force required to snap the pipe can be affected by various factors, such as the material and thickness of the pipe, the type of force applied, and the angle at which the force is applied.

5. What can we learn from the results of this experiment?

By analyzing the forces required to snap the pipe, we can gain a better understanding of the strength and durability of different materials and how they respond to external forces. This information can be applied in various industries, such as construction and engineering, to ensure the safety and reliability of structures and materials.
