- Sample Question 4 25 Marks A The State Of Stress At A Point Is Shown On The Element In Figure Q4 Construct Mohr S C 1 (58.7 KiB) Viewed 37 times
Sample Question 4 (25 marks) (a) The state of stress at a point is shown on the element in Figure Q4. Construct Mohr's circle, clearly indicating all important features, and use it to determine: i. The principal stresses (5 marks) ii. The orientation of the principal planes (5 marks) lii. The maximum in-plane shear stress and average normal stress at the point (4 marks) iv. The orientation of the planes on which the maximum in-plane shear stresses act (4 marks) (b) Using the Mohr's circle constructed in part (a), determine and sketch the equivalent state of stress if an element is oriented 60 counter clockwise from the element shown.
