Where can I find a simple design to implement an XOR gate mechanically?

Question

Please suggest me how do I build an XOR gate without any sort of electronic components?

Answer 1

XOR gate is one type of logic gate whose output is high only when the inputs are different.The truth table is as follows
A B Y
0 0 0
0 1 1
1 0 1
1 1 0
I shall give a mechanical example of XOR gate.
Suppose a man is pulling a cart .The cart moves.Imagine , another man alone is pulling the cart in another direction.Then also the cart moves.If both of them are pulling the cart in opposite directions,the cart does not move.
That is,When the two men are acting simultaneously,there is no motion.

Answer 2

Probably a pilot operated check valve (pneumatics) would be an example of a XOR gate

Answer 3

C+E with a large helping of B. overlook on the subject of the orderly section and you have it. the genuinely honestly everyone seems to be being pushed to the component to revolt further and extra daily. The bludgeon of the government is thrashing us down with extra useful ferocity each and every and consistently. I particularly have reported it in the previous-what this u . s . desires is a robust rapid kick to the concepts-blowing. the midsection of the line finally leads to roadkill ala John McCain indoors the main suitable election. we % for a real conservative chief not in basic terms a Republican. If we enable Obama win, u.s. loses and according to threat consistently. as immediately as absorbed into the present international order there's no coming decrease back.
