IV. [ Total: 20 pt. ] The state of two-dimensional plane stress at a point is shown on the element. Determine (a) the in-plane principal stresses and the directions where they appear. (b) the maximum in-plane shear stress, average normal stress, and the direction where the stresses occur. (c) The state of stress while the element oriented 50° clockwise from the position shown. Note: In (a) and (b), the corresponding orientation should be determined, and the results on each element should be sketched. [(a):7%, (b):7%, (c):6%] 70 MPa 40 MPa 50 MPa

Question: B10-4

This is a question based on the text book ‘’Mechanics of Materials’’ , please reply detail solution with instructions.(This is not a graded assignment. It's just a previous exam which I have finished and wanted to know the solution.)

* I will rate the reply with  “Like/Upvote,” if it is a complete step-by-step solution. 

* If it is an incomplete solution and there are some shortcuts of solution make me hard to understand, I will rate the reply with “Dislike/Downvote”.
