I have another view:
A masse suspended is a two opposed and equal forces system:
f = G - F
Where f = 0 if it is imobile.
So F = m * a and G = m * g; a = -g;
Its a bit basic, I know! A force and an acceleration do'nt have to be associated to a movement. A force to exist must be...
Hi there,
I have a simple question.
OR gate between 2 output TTL signals can be done with diodes and simply join the signals toguether... ?
Output TTL signals have a pull up resistor included:
For one output:
---------------
Output level 1) 5 V / -4 ma
Output level 0) 0.7 V / -16ma...
