Uploaded on Aug 19, 2010

I get this following information from youtube .I would like to share this knowledge to other please look at spinal sternosis youtube in the following . This youtube show about Spinal Stenosis causes symptoms similar to other back problems. Dr. Mazza and Dr. Stoll teach you how to identify your symptoms. They'll explain what role Imaging studies ply in identifying stenosis and what options are available to treat your back pain.

Dr. Emil DiIorio explains how to protect your back and prevent future back pain.

Calculation of Force on Car




If the weight of the car is N = lb, corresponding to
mass = kg = slugs,
and the car is traveling with a speed:
v = m/s = km/hr = mi/hr,
then a crash which stopped the car in a distance d=m = ft
would result in an average impact force of

Impact force F = N = lb = tons!!

You may change any data value. Clicking outside the box will then initiate a calculation of the impact force and conversion of the data value to the other types of units.

Car Crash Example

Force on Driver in Example Car Crash

For the car crash scenario where a car stops in 1 foot from a speed of 30 mi/hr, what is the force on the driver? Assume a 160 lb (mass = 5 slugs) driver.

If firmly held in non-stretching seatbelt harness: Stopping distance 1 ft.

  • Deceleration = 967 ft/s2 = 294 m/s2 = 30 g's
  • Force = 4813 lb = 21412 N = 2.4 tons
Non-stretching seatbelt
If not wearing seatbelt, stopping distance determined by nature of collision with windshield, steering column, etc. : stopping distance 0.2 ft.
  • Deceleration = 4836 ft/s2 = 1474 m/s2 = 150 g's
  • Force = 24068 lb = 107059 N = 12 tons!!
No seatbelt!
If seat belt harness stretches, increasing stopping distance by 50%: 1.5 ft.
  • Deceleration = 645ft/s2 = 197 m/s2 = 20 g's
  • Force = 3209 lb = 14274 N = 1.6 tons
Stretching seatbelt
These calculated numbers assume constant deceleration, and are therefore an estimate of the average force of impact.

SEATBELT PHYSICS

Seatbelt Physics

Non-Stretching Seatbelt

The task of the seatbelt is to stop you with the car so that your stopping distance is probably 4 or 5 times greater than if you had no seatbelt. A crash which stops the car and driver must take away all its kinetic energy, and the work-energy principle then dictates that a longer stopping distance decreases the impact force. For the example car crash scenario the stopping distance is one foot, the force on a 160 lb driver is about 4800 lb or 2.4 tons, and the deceleration about 30 g's. A moderate amount of stretch in the seatbelts will reduce the average impact force.

Stretching Seatbelt

A moderate amount of stretch in a seatbelt harness can extend the stopping distance and reduce the average impact force on the driver compared to a non-stretching harness. If the belt stretched 0.5 ft in the example car crash scenario, it would reduce the deceleration to 20 g's and the average impact force to 3200 lb compared to 30 g's and 4800 lb for a non-stretching seatbelt. Either a stretching or non-stretching seat belt reduces the impact force compared to no seatbelt.

No Seatbelt!

With no seatbelt to stop the driver with the car, the driver flies free until stopped suddenly by impact on the steering column, windshield, etc. The stopping distance is estimated to be about one fifth of that with a seatbelt, causing the average impact force to be about five times as great. The work done to stop the driver is equal to the average impact force on the driver times the distance traveled in stopping. A crash which stops the car and driver must take away all its kinetic energy, and the work-energy principle then dictates that a shorter stopping distance increases the impact force.

How far will the driver fly while the car is stopping?

When would you be better off not wearing your seatbelt?

With no seatbelt to stop the driver with the car, the driver flies free until stopped suddenly by impact on the steering column, windshield, etc. If the distance to impact is greater than 2 ft, the car will be at rest or even bouncing back when the driver strikes it at 30 miles/hr.

SPINE IMAGE AND EFFECTIVE AREA

CERVICAL LATERAL FLEXION

================================================================

Cervical Lateral flexion: Lateral flexion is another term for head tilt. Notice that the same bio-dynamics occur with head tilt as occur with head rotation. As the head tilts to the left, you can see the atlas rotate slightly posterior on the side of head tilt and anterior on the side opposite head tilt. C1 posterior tubercle swings to the right, followed by the spinouses of C2-C7 in a “Stair Step” effect with C7 spinous staying on the visual midline. The facets on the left side drop PI as the facets on the right side ride AS. This causes an obvious concavity of the cervical spine on the left and convexity on the right.

Cervical Curve Pattern (lateral view): Observe the x-ray animation of the cervical spine change from a slightly hyperlordotic curve, back through normalto hypolordotic to military to kyphotic. Notice that C2 through C7 must all move PI in order to straighten the cervical curve. This is normal bio-dymanics for a hypolordotic curve. If you were looking for individual vertebral misalignments, you would look to the segment or segments that stand out as being the most PI.
