Hello!
I am new to math forums and am not even sure I’m in the right thread but will give it a go!
I am trying to determine how many days it will take to mow 295 hectares when my mower has a blade 12’ wide and can move at 4km/hour.
Attached is what I believe to be correct but am uncertain if you can cross multiply squared numbers.
Thanks in advance!

You can cross multiply NUMBERS. How you got the numbers, by squaring or other wise, is irrelevant.
 
Ok - does this look correct to you then?

Right, ok so then do you believe the equation in the photo to be correct then?

Thread 'Derivation of equations of stress tensor transformation'

Hello ! I derived equations of stress tensor 2D transformation. Some details: I have plane ABCD in two cases (see top on the pic) and I know tensor components for case 1 only. Only plane ABCD rotate in two cases (top of the picture) but not coordinate system. Coordinate system rotates only on the bottom of picture. I want to obtain expression that connects tensor for case 1 and tensor for case 2. My attempt: Are these equations correct? Is there more easier expression for stress tensor...
