CARRIAGE DISTANCE

All about engine; Brake at the sight Of  obstruction
on the way . But when you see An obstruction, It takes some time To press the brakes .
At that time called. Reaction time .

this time should not be  More than 1/2 Second .

Because of

20 mails / Hour To go to this speed in 1/2 secounds
,

 And The bullish Car  has slips Further 20 Feet

 And the carriage Can move a lot Until The brakes stops.


THANK YOU
