A high-speed road or railway track that is poorly designed. The vehicle moves at constant speed from the straight segment of road or track directly onto a CircularArc and thereby encounters an instantaneous application of centripetal acceleration. This is neither good for the driver and passengers who will feel a sudden force outwards, nor for the vehicle which my skid and impose large stress changes in the axles and bearings.

This is why #Engineers use #TransitionCurves in the form of #CornuSpirals or #Clothoids to connect from the straight segment onto a circular arc. It has the property that it starts with zero #curvature at the beginning and then the curvature increases linearly with distance travelled along the curve. At the appropriate curvature, it is connected to a circular arc with the same curvature. The people in the vehicle and the vehicle itself are much less stressed by this solution.

Bridging The Gap Between Dissimilar Road Types With Foam

When you think of driving up or down an embankment, do you ever wonder how much foam you’re currently driving on? Probably not, because it hardly seems like a suitable building material. But …

Building Bridges In This Week’s Hack Chat

In the electronics world, even for the hobbyists, things have only gotten smaller over the years. We went from through-hole components to surface mount, and now we’re at the point where the e…
