Simple Machines - Gear

This Simple Machines Gear model demonstrates the principle of rack and pinion mechanics-a vital component in many real-world technologies. Designed with sturdy wooden parts, this apparatus allows students to observe how rotational motion is transformed into linear movement, and vice versa. By turning the pinion (circular gear), the rack (gear bar) moves back and forth, offering a clear and practical understanding of motion conversion.

Educational benefits:

• Shows how gears transmit motion and force
• Demonstrates real-life engineering applications like steering systems and railways
• Encourages hands-on exploration and mechanical reasoning
• Supports STEM education through model-based investigation

Classroom activity ideas:

• Compare rotational and linear motion using pinion-to-rack movement
• Explore direction reversal and force when adjusting gear pressure
• Discuss how the model mimics real-world mechanisms like elevators or trains
• Use the gear to investigate friction and efficiency
