Simple Machines - Pulley

The Simple Machines Pulley Model brings one of the most widely used simple machines to life in your classroom. Designed with strong, durable materials and clear visibility, this wooden apparatus allows students to investigate how pulleys make lifting easier by offering mechanical advantage. Whether lifting a flag, moving construction materials, or hoisting theatre curtains, pulleys are essential tools in real-world engineering-and this model helps learners explore these concepts through hands-on experimentation.

Educational benefits:

• Demonstrates how single and multiple pulleys influence force and direction
• Supports both qualitative observation and quantitative analysis
• Encourages hypothesis testing through inquiry-based learning
• Develops understanding of mechanical advantage and load distribution

Classroom activity ideas:

• Compare the force required to lift weights using one, two, or three pulleys
• Conduct experiments on directional change and energy efficiency
• Explore pulley applications in cranes, hoists, and elevators
• Challenge students to design a lifting system using the model

Specifications

• Made from particle board and MDF components
• Includes instruction manual for student and teacher use
• Model base measures 16.5 cm (L) x 8.9 cm (W) x 41 cm (H)
• Sturdy enough for repeated classroom handling and experimentation
