Enough is enough...
Any newbie in any field can think up many more questions and spit them out faster than they can be answered.
This question has been asked repeatedly in this and other forums, you did not bother to search for an answer already given.
This forum is supposed to be an EXCHANGE of information...not a one way street....
Your particular long list of questions indicates to me that you wish to be "spoon fed" a course in tank design....with no effort on your part.
Do you reside in Iran ??? What is your native country ??
Purchase a few books on tank design
