Question 1201665
.


Hello, this site is for helping school students in Math.


Your problems and questions are from totally different area (it is even not a school Physics - 
it is Mechanics of Materials). I do not think that there is a tutor at this forum
who is able answer your questions - not because we are so stupide, but because
your questions are from very different area.



To come to this forum with such questions is the same as to go to a grocery to buy a hardware.



Therefore, my advise to you is do not spend your valuable time for nothing
and do not embarrass us, the tutors.


Find another, more appropriate web-site for your questions to satisfy your curiosity.
