From levers to pulleys, and inclined planes to wheel and axles, we’ll explore the different types of simple machines used in Rube Goldberg devices and share some creative ideas to get you started.
Components of Rube Goldberg Simple Machines
A Rube Goldberg machine, named after the famous cartoonist Reuben Rube Goldberg, is a complex device that consists of a series of simple machines working together to accomplish a specific goal, such as knocking over a domino or turning on a light. These machines are characterized by their creativity, complexity, and chain reaction mechanism. The key components of a Rube Goldberg machine include various types of simple machines that work together to create an impressive and often humorous spectacle.
Lever
A lever is a simple machine that consists of a bar or rod that pivots around a fixed point called the fulcrum. The fulcrum serves as a pivot point, allowing the lever to move up and down or side to side. The force applied to the lever is transmitted to the load, making it easier to lift or move. In Rube Goldberg machines, levers are often used to change the direction of motion or to amplify the force applied to a load. A lever is typically used in situations where a small force is needed to achieve a larger result.
The following are some examples of levers used in Rube Goldberg machines:
- Rocking Levers: A rocking lever is used to lift a lever up or down, creating a movement that triggers another simple machine in the chain reaction.
- See-Saw Levers: A see-saw lever is used to lift a load up or down, often used in combination with other simple machines to create a complex motion.
- Pendulum Levers: A pendulum lever is used to create a swinging motion, often used to launch a load or trigger another simple machine.
Pulley
A pulley is a simple machine that consists of a wheel or grooved block with a rope or cable wrapped around it. The rope or cable is used to lift or move a load by changing the direction of the effort applied to it. Pulleys are often used in Rube Goldberg machines to change the direction of motion or to amplify the force applied to a load. There are two main types of pulleys: single pulley and double pulley.
The following are some examples of pulleys used in Rube Goldberg machines:
- Single Pulley: A single pulley is used to lift a load up or down, creating a movement that triggers another simple machine in the chain reaction.
- Double Pulley: A double pulley is used to change the direction of motion, often used in combination with other simple machines to create a complex motion.
- Block and Tackle Pulley: A block and tackle pulley is used to amplify the force applied to a load, often used in situations where a small force is needed to achieve a larger result.
Inclined Plane
An inclined plane is a simple machine that consists of a sloping surface or ramp used to lift or move a load. The force applied to the load is reduced as the load is moved up the inclined plane, making it easier to lift or move. In Rube Goldberg machines, inclined planes are often used to change the direction of motion or to amplify the force applied to a load.
The following are some examples of inclined planes used in Rube Goldberg machines:
- Rolling Inclined Plane: A rolling inclined plane is used to move a load up or down, creating a movement that triggers another simple machine in the chain reaction.
- Sliding Inclined Plane: A sliding inclined plane is used to lift a load up or down, often used in combination with other simple machines to create a complex motion.
- Cylindrical Inclined Plane: A cylindrical inclined plane is used to amplify the force applied to a load, often used in situations where a small force is needed to achieve a larger result.
Wheel and Axle, Ideas for a rube goldberg simple machine
A wheel and axle is a simple machine that consists of a circular wheel attached to an axle, used to change the direction of motion or to amplify the force applied to a load. The wheel and axle can be used to lift, move, or rotate a load, making it easier to perform complex tasks. In Rube Goldberg machines, wheel and axles are often used to change the direction of motion or to amplify the force applied to a load.
The following are some examples of wheel and axles used in Rube Goldberg machines:
- Bicycle-Type Wheel and Axle: A bicycle-type wheel and axle is used to create a circular motion, often used in combination with other simple machines to create a complex motion.
- Cart Wheel and Axle: A cart wheel and axle is used to amplify the force applied to a load, often used in situations where a small force is needed to achieve a larger result.
- Turntable Wheel and Axle: A turntable wheel and axle is used to rotate a load, often used in Rube Goldberg machines to create a complex motion.
Tips for Building Rube Goldberg Simple Machines: Ideas For A Rube Goldberg Simple Machine
Building a Rube Goldberg machine can be a fun and creative project, but it requires some planning and execution to avoid common mistakes and achieve a smooth and satisfying chain reaction. In this section, we’ll provide step-by-step instructions on how to build a basic Rube Goldberg machine, discuss common mistakes to avoid, and offer suggestions for troubleshooting and refining your machine.
Step-by-Step Instructions
To build a basic Rube Goldberg machine, you’ll need a series of simple machines, such as marbles, ramps, levers, pulleys, and inclined planes. Here’s a simple example:
- Start with a marble at the top of a ramp. The marble will roll down the ramp and strike a lever, which will be connected to a seesaw.
- The seesaw will swing up and hit a pulley, which will release a string and pull up a ball.
- The ball will then roll down an inclined plane and hit a block, which will be connected to a spring.
- The spring will then release the block, which will roll down a ramp and hit a button, triggering a bell to ring.
This is a very basic example, but it showcases the chain reaction that occurs in a Rube Goldberg machine.
Common Mistakes to Avoid
Here are some common mistakes to avoid when building a Rube Goldberg device:
- Insufficient planning: Before building your machine, think through the entire chain reaction and make sure it’s feasible and logical.
- Inadequate testing: Test your machine thoroughly before displaying it to make sure it works as intended.
- Inconsistent measurements: Make sure all the components are proportional and match the design plan.
- Using unstable structures: Ensure that all the structures are stable and won’t collapse under their own weight or when triggered.
These mistakes can be frustrating and time-consuming to fix, so it’s better to avoid them altogether.
Troubleshooting and Refining
Always test your machine before it falls apart!
If your machine doesn’t work as intended, here are some common issues and solutions:
| Issue | Solution |
|---|---|
| Marbles get stuck | Use lubricant or a smooth surface to help the marbles move. |
| Seesaw doesn’t swing | Adjust the pivot point or use a different seesaw design. |
| Pulley doesn’t release | Check the connection between the pulley and the string. |
By identifying and addressing these common issues, you can refine your machine and achieve a smooth and satisfying chain reaction.
If you’re facing more complex issues or want to further refine your machine, you may need to experiment with different designs or components. Remember to have fun and be creative!
Creative Ideas for Rube Goldberg Simple Machines
Rube Goldberg machines are a fusion of art, science, and creativity.
