A LITTLE PHYSICS
FOR BETTER UNDERSTANDING OF THE MOTOR BIKE.

• braking
• turns
• variation

Calculation of the braking distance.

Note:

In this theory, the braking is considered as perfect and the motor bike does not skid
The braking distance increases with the square speed. If the speed is doubled, the distance become de quadruple.
Make all calculations which you will want will not be able to never stop you on 100 m with 200 km/h unless it is not against a wall or a pillar.
The laws of physics are hard but they are inviolable laws (even by the politicians, the ambassadors, the princesses, the artists and all the people known as influential).
To decrease the braking distance it is necessary to use means which do not call upon adherence on the road.
It is necessary to:

• have a parachute,
• have retrorockets,
• drop anchor,
• reverse the push of an engine,

All these means are not very practical for a motor bike. Then...

PRUDENCE AND CONTROL YOUR SPEED

To avoid to break your head you can use the form. It is based on this theory.
The distance covered during the reaction time of the pilot and mechanics is added.

Turns.

Instructions of the form

Enter the speed to which you take your favorite turn.
Enter the angle taken.
Enter the new speed to which you wish to take this turn.
Click " To calculate "
The form calculation the radius of curvature and the new angle to be taken.

Data Speed ............ km/h Angle ............  degrees New speed......... km/h Results Radius............ m New angle ........ degrees

Note:

There are no miracles, we must limit our speed in the turns.

PRUDENCE AND LET US CONTROL OUR SPEED

Calculation of the angle taken to avoid an obstacle

All motard tested this perilous situation, which consists with this brutally finding with an obstacle to circumvent.
It is too late to slow down.
To avoid the crash, you must do two curves.
Therefore angle should be taken.
The form calculation according to:
- your speed,
- the distance from the obstacle,
- the variation to carry out

the radius of the curves (simple Pb of geometry)
and the angles which should be taken which are opposite directions and of the same absolute value.

I consider that the pilot is excellent and that it has the good reflex to change angle.

Data Speed ............. km/h Distance........... m «Ecart »........... m Results Radius of the curves. m Angle................ degrees

Note:

Have fun with this simulation.
Test all the most eccentric cases.
But on the road:
