• Hey it's me, Destin. Welcome back to "Smarter Every Day." We're at that magical moment where you build something in the garage, a culmination of week and a half of effort and then you kind of all have your hands in your pockets. This is Jeremy filming.

Key Insights

• 🫥 Weed eater lines with larger bend radius and rigidity are generally stronger.
• 🫥 Objects such as posts and fences can cause the lines to wrap around and break off, leading to the loss of the line.
• 🫥 The tournament-style test allowed for a fun and interactive way to determine the strength of different weed eater lines.
• 🚄 High-speed cameras were vital in capturing the interactions between the lines and the objects they hit.
• 😤 The team acknowledges that the results of the test may not be scientifically accurate due to human errors in judging the outcomes of the battles.
• 😂 The video highlights the importance of having a bend radius that allows for toughness and prevents tearing in weed eater lines.
• 😂 The championship battle revealed that lines with a larger bend radius and more rigidity were more resistant to breaking or tearing.

Questions & Answers

Q: What is the purpose of the tournament-style test in this video?

The purpose of the tournament-style test is to determine the strength of different weed eater lines and identify which line is the strongest through a series of battles.

Q: How does the team test the lines' strength?

The team builds a device with an old school oscilloscope protomatic and sets the angle of the lever. They connect the weed eater lines to the lever and use throttle controls to simulate the movement of the weed eater. The high-speed camera captures the interactions between the lines and objects.

Q: What factors are considered in determining the strength of the lines?

The team analyzes factors like bending radius, tearing, and the ability of the lines to withstand the impact and wrapping effect when hitting objects.

Q: What did the team discover about the strongest weed eater lines?

The team found that lines with a larger bend radius and more rigidity tend to be stronger. These lines were less likely to tear or break during the battles.

Summary & Key Takeaways

• The Smarter Every Day team builds a device to test the strength of different weed eater lines and sets up a single elimination tournament to determine the strongest line.

• They use high-speed cameras to capture the interactions between the lines and the objects they hit, analyzing factors like bending radius and tearing.

• After intense battles, the team discovers that lines with a larger bend radius and more rigidity tend to be stronger.
