Bridges
From simple footbridges to massive steel structures, a bridge is the perfect way to cross from one place to another. In this BrainPOP UK movie, you’ll see examples of the three different types of bridges: post and beam; arched; and suspension. Plus, in this educational, animated movie find out how the forces of gravity, tension and compression must all be taken into account when designing a bridge, if it is going to be safe. After all, we don’t want a repeat of London Bridge! |
