Did ancient Babylonians anticipated integral calculus with velocity v time graphs!

From a New York Times article Signs of Modern Astronomy Seen in Ancient Babylon Which begins: For people living in the ancient city of Babylon, Marduk was their patron god, and thus it is not a surprise that Babylonian astronomers took an interest in tracking the comings and goings of the planet Jup...

Why don't you use the A & B Coefficients in mSMAC?

Q: Why do we not input both A and B for the stiffness information? I am sure there is something fundamental to this approach! A: SMAC dynamically models the loading and unloading of the vehicle structure so the CRASH 'A coefficient' is not needed. The AKV (crush stiffness input for SMAC) is similar...

Does SMAC underreport the impact duration?

Q: I think it is a fair statement that smac under-reports the impact duration, generally if not always. My understanding is that the duration is shorter because the “unloading” or “restitution” phase is not calculated after max engagement. Instead, the restitution forces are “added” at the end of ea...

Re: Is there a tire friction variation in cooler temperatures?

In an earlier post we mentioned we would include any changes to the Northwestern Table of friction coeffiecients; The 2010 version of the Northwestern Traffic Crash Reconstruction, 2nd Edition book no longer includes a table and includes discussion, portions of which are as follows: from p 142, Tabl...
