Question

Question 1: A strain gauge is bonded to the surface of a component made from 7075-T6 Aluminium Alloy (E=71.7GPa, v = 0.33, Oy = 503MPa) shown in Figure 1.1. For the strain gauge data given, using the graphical method, construct the Mohr's strain circle and determine the following: • • • • The Maximum and Minimum Principal Strain, &i and &z respectively The angle that ea makes with £1 The Maximum and Minimum Principal Stress, 01 and 2 respectively The equivalent von Mises stress Will yielding occur at that point? E Figure 1.1: Schematic of strain gauge (Note: Not to scale)

Hi! Can someone be solve the 5 sub-questions presented in this question please? I'm currently studying for my mechanics of solids class and I'm still having a difficult time understanding this concept. Thanks in advance!
