Simple Machines in Rube Goldberg Machines

Rube Goldberg machines are clever contraptions that demonstrate the chain reaction principle, where a series of events is triggered to achieve a final goal. Simple machines play a crucial role in these elaborate machines, as they are used to magnify or change the direction of force to create a chain reaction. In this section, we will explore how simple machines are used in Rube Goldberg machines and compare their applications with practical uses.

Types of Simple Machines in Rube Goldberg Machines

Simple machines are used to create a chain reaction in a Rube Goldberg machine by transferring energy from one machine to another. There are six basic simple machines: lever, pulley, wheel and axle, inclined plane, wedge, and screw. In a Rube Goldberg machine, each simple machine is used to trigger the next one in the sequence.

• Lever: A lever is a bar that pivots around a fixed point called a fulcrum. In a Rube Goldberg machine, a lever is often used to lift or move a weight to trigger the next event. For example, a large metal beam might be used as a lever to lift a metal ball that rolls down a track, striking a smaller ball and setting off the next stage of the machine.
• Pulley: A pulley is a wheel with a grooved rim and a rope or cable wrapped around it. In a Rube Goldberg machine, a pulley is used to change the direction of the force applied to it. For instance, a large rope wrapped around a pulley might lift a heavy weight, which in turn triggers a chain reaction.
• Wheel and Axle: A wheel and axle is a machine that consists of a wheel attached to a rod or shaft. In a Rube Goldberg machine, a wheel and axle is often used to lift or move a weight over a long distance. For example, a large wheel attached to an axle might be used to roll a heavy log that strikes a domino, triggering the next event.
• Inclined Plane: An inclined plane is a surface that is tilted at an angle. In a Rube Goldberg machine, an inclined plane is often used to lift or move a weight up a steep slope. For instance, a large inclined plane might be used to roll a metal ball up a steep slope, striking a bell that sets off the next stage of the machine.
• Wedge: A wedge is a triangular tool that is used to split or separate objects. In a Rube Goldberg machine, a wedge is often used to trigger a chain reaction by splitting a beam or striking a bell. For example, a large wedge might be used to split a wooden beam that strikes a bell, triggering the next event.
• Screw: A screw is a machine that consists of a rod with a spiral thread. In a Rube Goldberg machine, a screw is often used to lift or move a weight over a long distance. For instance, a large screw might be used to lift a heavy weight, which in turn triggers a chain reaction.

Practical Applications of Simple Machines in Rube Goldberg Machines

Simple machines used in Rube Goldberg machines are similar to those used in practical applications, such as construction and manufacturing. In construction, simple machines like levers and pulleys are used to lift and move heavy loads, while in manufacturing, simple machines like screws and wedges are used to assemble and disassemble products. In Rube Goldberg machines, these simple machines are used in a creative and playful way to demonstrate the chain reaction principle.

Simplifying complex machines using levers and pulleys is easier to understand.

Types of Simple Machines Used in Rube Goldberg Machines

Rube Goldberg machines often employ the following types of simple machines to achieve their intended outcome.

• Pulleys
  A pulley system is used in Rube Goldberg machines to change the direction of force or motion. It typically consists of a wheel or grooved pulley wheel with a rope or cable wrapped around it. When the rope is pulled, the pulley wheel turns, transferring the force to another location, often lifting or moving an object. Pulleys are an essential component in many Rube Goldberg machines, helping to lift heavy objects, rotate wheels, and even launch objects into the air.

  For example, a classic Rube Goldberg setup might use a pulley system to lift a heavy ball, which then rolls down an inclined plane, striking a switch and triggering the next event in the chain reaction.

• Levers
  A lever is used in Rube Goldberg machines to magnify the force applied to an object. It consists of a fulcrum, a pivot point, and a lever arm. When the lever is pushed or pulled, it transfers the force to the object, often resulting in a significant increase in the force applied. Levers are commonly used in Rube Goldberg machines to open doors, lift heavy objects, and move heavy structures.
• Inclined Planes
  An inclined plane is used in Rube Goldberg machines to change the direction of force or motion. It consists of a flat surface tilted from the horizontal, where an object can roll or slide down. The inclined plane can be used to move heavy objects, launch objects into the air, or even drive a mechanism. Inclined planes are often used in combination with other simple machines to create complex and creative chain reactions.

Practical Applications of Simple Machines in Rube Goldberg Machines

The use of simple machines in Rube Goldberg machines has several practical applications.
