Building Bridges: Engineering Principles Introduced
Year 8 Technology Lesson 1 of 9 Introduction to Structural Engineering
Why Do We Need Bridges?
Think about your journey to school What obstacles do bridges help us overcome? How do bridges connect communities?
What is Engineering?
Solving problems through design and innovation Using science and mathematics to create solutions Making life better for communities Turning ideas into reality through careful planning
Forces Acting on Bridges
Types of Bridge Forces
{"left":"Compression: Forces that squeeze or push materials together\nTension: Forces that stretch or pull materials apart","right":"Load: The weight that the bridge must support (cars, people, wind)\nSupport: Upward forces from foundations and pillars"}
Measurement Matters!
Why is accuracy crucial in engineering? Practice measuring classroom objects Record measurements in metric units Discuss what happens when measurements are wrong
Real-World Bridge Examples
Sydney Harbour Bridge - steel arch design Story Bridge Brisbane - cantilever construction Westgate Bridge Melbourne - cable-stayed design Each design handles forces differently
Engineering Challenge Ahead
"Good engineering is not just about making things work - it's about making them work safely, efficiently, and sustainably for everyone." Next lesson: We start designing our own bridge models!
