Why do some small bridges have weight limits that depend on how many wheels or axles the crossing vehicle has?

So this podcast series is all about gasses, and the gas is defined as a substance or matter that is in a particular state that will allow it to freely expand to the entire container, and it will have no fixed shape or volume. So what we need to be considering here is pressure, and so pressure is the force acting per unit area of the object. This is inversely proportional to the area of contact. And so if we have a situation where we have vehicles with the exact same load but a different number off axles, this will look Zack. Different pressures on the bridge. So when the vehicle has a greater number of Axl's, the area of contact attacked is increased on. This reduces the pressure because we know that these air inversely proportional. So if we increase pressure, then we have a low area on with that reduce pressure. What we see is less wear and tear on the bridge itself. So now we can consider the case of the vehicle having less axles or wheels on the total force is concentrated over a smaller surface area. So if we remember our relationship, if we have a greater area than we have a reduced pressure. But now if we think of the opposite, if we have a lower area, then we have a higher pressure and this increases the wear and tear on the bridge. And so small bridges have weight limits that depend on the number of whales or exhales crossing it.
