L10 to L16 I think it would be enough and all the other I think it is questionable... Maybe you have something in thoughts you can share? Because it maybe easier for our senior to understand if you have a justification. For ex. L17 is not reasonable because it is just like two situation occur but stress/force..etc. are being subtracted.(I realy dont know how to say it...but all I know is,"It is wrong".)

Please send me a PM with your opinion cause I am realy excited to know your justifications..

Salamat...
