Identify two types of simple machines that are included in a Rube Goldberg machine.
Pick any simple machines: For example, wedge, and lever.
To identify two types of simple machines included in a Rube Goldberg machine, we need to understand what simple machines are. Simple machines are basic mechanical devices that use mechanical advantage to simplify work. They operate on fundamental principles of physics and allow us to do work with less effort.
A Rube Goldberg machine is a complex contraption that performs a simple task in a complicated and indirect way using a series of chain reactions. These machines often incorporate various types of simple machines to achieve their purpose.
Here are two examples of simple machines that are commonly found in Rube Goldberg machines:
1. Lever: A lever is a simple machine consisting of a rigid bar or beam that pivots around a fixed point called a fulcrum. It helps in amplifying or redirecting forces. In a Rube Goldberg machine, a lever can be seen, for instance, when a falling ball hits one end of a seesaw, causing the other end to rise and trigger the next step.
2. Pulley: A pulley is a simple machine consisting of a grooved wheel with a rope or cable running through it. It can be used to change the direction or magnitude of a force. In a Rube Goldberg machine, a pulley might be employed when the movement of a rock falling from a height causes a rope to go through a series of pulleys, which eventually raises a weight to trigger the subsequent step.
These are just two examples, but a Rube Goldberg machine can incorporate many other simple machines like wedges, inclined planes, screws, wheels and axles, etc., depending on the creativity and complexity of the design.
