What Parts Work Together?
How do engineers manage to cut through a mountain to make way for a highway? The process involves numerous parts and tools working together. Engineers start by studying the mountain to understand its shape, rock types, and possible challenges. They use big machines, like excavators and bulldozers, to dig, break, and move rocks and dirt. Dynamite is sometimes used to blast away very hard rock. Support beams and walls help prevent the sides from caving in while working.
👀 Visualize This: Imagine a cross-section of a mountain with a highway running through it. Draw the machines and tools used to cut and stabilize the path. Include an excavator and a support wall. Where do you see force being applied?
Pause & Think: What do you think would happen if the support beams weren't used?
