Muddy Card Responses Lecture M11 Clarify a bit more on tensors. A bit confused. We will go over the aspects of tensors we need to use as we apply them to stress and strain tensors. In Einstein notation how do you tell the difference between F ij and F ik seems like both of these are F i1 +F i2 +F i3 , but there is obviously a difference (as in s 21 + s 23 )? There is no functional difference, i, j, k. or for that matter p, q and r are just dummy symbols, that take values 1, 2 or 3. Remember the function of the indices is to indicate whether there are separate equations or summation across the indices, depending on whether the indices appear once or twice in a particular term. Last PRS question - confused?. I will put this up again at the beginning of the next lecture. In the meantime you can look at the question and the solution at the bottom of these muddy responses. Please better explain the last PRS question (maybe another to make sure we got it). See previous response.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
