A little story about a cyclist ..

1
A little story about a cyclist ..
..and a bit of physics.
2
Would you drive a car like this?
3
Maybe?
Then there is a good chance you would end up like
this
4
Have they not heard of my Laws of motion?
If you travel too close to the person in front
then you will not be able to stop in time
If you fall off then gravity pulls you to
downwards
When skin and road surface meet skin wears off
before the road surface
5
These guys ignored Newton at their peril
6
Would this guy ignore Newton?
You would think he would know better
7
Yes he did
8
One artist impression
9
And another
10
But it was very close to this
11
The outcome.
Smashed helmet and concussed
Damaged shoulder joint
Broken Leg at the hip
Lost skin from shoulder thigh and legs
12
But wait.. Physics comes to the rescue!
13
Physics discoveries helped design many of the
features of this handy machine
14
The discovery of xrays enabled us to see the
bones through the flesh to check for breaks..
15
And this is my hip can you see the break?
16
And here is how it was fixed bolted together
with 3 bolts
All it required now is 3 or 4 months to heal.
17
And the shoulder
No break just a damaged joint
18
A knowledge of Physics designed this helmet that
saved my head
Foam lining broke to reduce the impact
Surface scraped of on the road
19
To check that there was no bleeding around the
brain a special x-ray device all CT was used
20
This shows the slices of the brain that were
imaged
21
And this this is one of the x-ray images
22
An another imaging process called MRI was used
for even better images.
23
And apparently, nothing significant was
found!!!!
24
The moral of the story is
Even if you (stupidly) ignore Physics..
It may save you to ride another day
25
However if everything else fails then one could
try the more traditional Chemical cure.
