Ever wondered what's inside these barrels? Click to find out!
You’ve probably seen them several times on the side of the road. They’re placed strategically in front of fixed objects and will take the impact if a driver runs into them. For a brief explanation of how this happens, let’s take a look at this excerpt from our blog post onThis is by no means a physics blog, but a basic grasp of how energy works is needed to understand attenuators …
But, if a vehicle stops by crashing into a wall, the energy is dispersed very suddenly, resulting in a car that’s crushed. Attenuators won't exactly give a soft landing, but they do work to dissipate the energy slowly like your brakes do.They can be set up in different configurations depending on speed limits and the specifics of the location.
The weight of each barrel varies – they weigh 200, 400, 700 or 1,400 lbs. The lightest barrels are placed in front and they get progressively heavier to handle the impact, absorb and dissipate the energy of a crash.
