Some Momentum Misconceptions

Some comments on Momentum analysis: (1) The collision between two vehicles is not the same as a collision between two pool balls. More like two crushable rectangular boxes on wheels. And vehicles are not 'balls' or 'points', they are finite dimensioned crushable objects which may behave quite differ...

DeltaV in terms of G's?

Q: I am used to discussing Delta -V for the forces on a person in a crash. Another expert is using G's. What is the conversion from one to the other? A: DeltaV, or Impact speed change, is normally associated with a collision. (to avoid those among you who will say `but you encounter a DeltaV when br...

What it the "Ball Bank Indicator" and what does it measure?

The term " Ball Bank Indicator " refers to an inclinometer that is used for the specific purpose of determining safe (uniform advisory) curve speeds for horizontal curves. It measures the overturning force (side friction), measured in degrees, on a vehicle negotiating a horizontal curve - whether it...
