My automotive and aircraft maintenance expertise leads me to deduce that the steering functionality of the car was adversely affected by the failure of the schveigle valve in the pressurized side of the power steering sub-assembly.
Old habits !.
In and before the 60's we (in the UK ) could drive to the pub have a couple of pints, and still go (by car) for an evening dinner later, have wine or beer with your meal then drive home without hitting anything in our way home again.
The Good Old Days. LoL
In the G.O.D.s if you hit something solid in your car, chances are that you would be severely injured as a result of your body colliding with the interior or the car. Now we travel securely attached to the inside of the vehicle with parts of the interior designed to pop out at you to restrict how far you move. The interior of the car is covered with energy-absorbing material. The cabin of the car is designed to remain undeformed while the rest of the car progressively crumples to dissipate energy and to reduce the momentum pulse.
The introduction of random testing for alcohol has dramatically reduced the usual blood alcohol levels of affected drivers from pre-random testing levels. In 1982 the number was 1253 (23.6 deaths per 100,000 people). RBT was introduced on 17 December 1982, and from then on the fatality rate has steadily declined. In 2018, 353 lives were lost in traffic collisions in NSW. Unfortunately, the explosion in the use of drugs by that section of the population which has the least experience in driving has not reduced the crash rate.
There will always be a base line of road fatalities due to unforeseeable circumstances (medical causes; true accidents, and vehicle or roadway failures). It is the foreseeable causes - intoxication, fatigue, stupidity that we must try to eliminate firstly by education, and secondly by penalty.
On YouTube there is a Chevy Malibu being crash tested with an old model Chevy. It is very scary vision. I like old solid cars, but it is ridiculous how much caves in on the dummy. The new car crumples but pax compartment stays intact.
Worth a look.
The crumple zones work but of limited help if the velocity gets higher. Side impact is less effective also as the distance for it to "work" is restricted.. Generally this is a good move but visibility has been sacrificed with thicker forward and centre pillars. Nev
Of course the value of crumple zones is limited by the Force of the impact, which is mainly dictated by the velocity of the bodies at impact. The reason for having crush zones is that they extend the time over which the impact force is applied, thereby reducing the rate of acceleration (or deceleration in an collision) of the struck object. In occupant safety, this reduction in the rate of deceleration helps the human body to survive the collision forces.
In classical mechanics, impulse (symbolized by J ) is the integral of a force, F, over the time interval, t, for which it acts. It is the rate of change of Momentum
Momentum = mass x velocity
M = mv
where F is the resultant force applied, t1 and t2 are times when the impulse begins and ends, respectively, m is the mass of the object, v2 is the final velocity of the object at the end of the time interval, and v1 is the initial velocity of the object when the time interval begins.
The longer the time over which a force is applied reduces the magnitude of the impulse.
Imagine you are playing golf. The idea is to move a ball of known mass over a distance. The usual way is to apply a large force to the ball for a short time:
The impulse, J, is high because the force is applied for a very short time. And because the golf ball is very resistant to deformation, the majority of the force is used to acceleration the ball, i.e. to increase its velocity. Try getting the same distance when you hit a squash ball, which will deform at when the golf stick hits it.
Another function of crumple zones is to dissipate the impact force by using it to deform the structure of the body and create noise, which is the result of directing impact force to the surrounding air to dissipate it as energy waves in air.
Bending the metal ends up as heat . Everything ends up as heat (entropy) at a low temperature level ,so not very useful. by then. Infra red and micro wave would be more effective than sound waves at moving heat energy. .You can make a lot of noise and not get anywhere.. Nev
I still like the old idea of mass hitting lesser mass resulting in greater damage to the smaller vehicle, like the Arab state outlawing small cars, as they are less likely to protect the occupants, when hit by a 3 1/2 ton high speed car.
