Engineering Merit Badge Requirement 6 Helps and Answers

Creating a Simple Motion Model: Levers and Inclined Planes

For the Engineering merit badge, you can build a simple model that demonstrates motion using basic mechanical elements like levers and inclined planes. Here’s how you can do it and what you’ll learn.

Building a Lever and Inclined Plane Model

Materials Needed:

  • A ruler or flat piece of wood (for the lever)
  • A small object like a toy car or a ball (to move)
  • A stack of books or a block (as a fulcrum)
  • A piece of cardboard or a plank (for the inclined plane)

How It Works:

  1. Lever:
  • Place the ruler on the block, with one end longer than the other. The block acts as the fulcrum, and the ruler is the lever.
  • Place the toy car or ball on the short end of the lever.
  • Push down on the long end of the lever to lift the object on the other side.
  • This demonstrates how a lever can move an object by applying force on one side to lift something on the other side.
  1. Inclined Plane:
  • Place the cardboard or plank against the stack of books to create a ramp.
  • Roll the toy car or ball down the inclined plane.
  • This shows how an inclined plane allows objects to move smoothly from a higher point to a lower point using gravity.
How These Elements Demonstrate Motion
  • Levers use a fulcrum to change the direction of a force, making it easier to lift or move heavy objects. The longer the lever, the less force you need to apply to lift the object on the other side.
  • Inclined Planes reduce the amount of force needed to lift an object by spreading the work over a longer distance. Instead of lifting something straight up, you can slide it along the plane, which requires less effort.
Real-World Example: Wheelbarrow

A wheelbarrow is a common tool that uses both a lever and an inclined plane. The handles of the wheelbarrow act as levers, allowing you to lift and move heavy loads more easily. The wheel acts like an inclined plane when you push it forward, making it easier to move the load over a distance.

By building this simple model, you see how basic mechanical elements like levers and inclined planes work together to create motion. These principles are used in many real-world tools and machines to make work easier. Understanding these concepts is an important part of the Engineering merit badge, as it helps you learn how engineers design systems to move and lift objects efficiently.
