Lesson Express
Q: What features help the tracked vehicle shredder move smoothly over rough ground?
A: The tracked vehicle shredder has large, wide tracks, called caterpillar treads, which help it grip the ground and move smoothly over rough or uneven surfaces.
Q: How is the tracked vehicle shredder similar and different from a skateboard or snowboard?
A: The tracked vehicle shredder is similar to a skateboard or snowboard because you can stand on it while it moves over the ground. Both need a surface to ride on, but a skateboard or snowboard works best on flat surfaces, like a smooth road or snow-covered hill. In contrast, the tracked vehicle shredder uses caterpillar tracks and allows it to navigate over different types of areas, such as dirt, mud, or rough ground.
Q: Why do you think shock absorbers are important in a tracked vehicle shredder?
A: Shock absorbers are important in a tracked vehicle shredder because they help the machine handle bumps and rough areas. When the shredder moves over uneven ground, the shock absorbers cushion the impact; this makes the ride smoother.
