Jenga Physics and Actuator Challenges

The video explores the mythically impossible move in Jenga, where removing a single brick from a late-stage game without toppling the tower is deemed impossible. Valerie proposes using a pneumatic actuator to test this myth. Initial tests with supersized blocks fail due to weight issues, leading to adjustments and retesting with standard blocks. The final tests, including a bike and fishing line setup, demonstrate that the impossible Jenga move is indeed possible, with the pneumatic actuator achieving success at 120 PSI.

What is the main challenge in the mythically impossible Jenga move?

• Removing a brick from the middle of the tower

• Removing a brick from the top of the tower

• Removing a single brick on which the whole tower rests

• Removing two bricks simultaneously

What inspired Valerie to use a pneumatic actuator?

• Her background in robotics

• Her love for puzzles

• Her interest in physics

• Her experience with Jenga

What was the main issue with using supersized Jenga blocks?

• They were too slippery

• They had too much weight pressing down

• They were too colorful

• They were too light

Why did the team decide to revert to standard-sized Jenga blocks?

• To correct the physics of the test

• To make the game more challenging

• To make it easier to see the blocks

• To use less material

What did the team learn about scaling objects in physics?

• Scaling up makes objects lighter

• Scaling up has no effect on weight

• Scaling up affects both size and weight

• Scaling up only affects the size

What was the result of the final test with the pneumatic actuator on standard-sized blocks?

• The block was removed but the tower wobbled

• The actuator failed to move the block

• The tower remained standing

• The tower collapsed immediately

What nickname was given to Allie during the test?

• Speedster

• Champion

• Crash

• Jenga Master

What was the impact velocity of the pneumatic actuator in the successful test?

• 60 miles per hour

• 50 miles per hour

• 90 miles per hour

• 75 miles per hour

What was Valerie's reaction to the successful test?

• She was amazed

• She was confused

• She was indifferent

• She was disappointed

What was the final conclusion about the mythically impossible Jenga move?

• It is only possible with supersized blocks

• It is impossible

• It is possible with the right tools

• It is a myth with no basis
