Question 7 A delta strain gauge rosette (60° angles between gauges) bonded to a magnesium alloy component, measured microstrain readings of 300, -240 and 60. Determine the principal strains and from them the principal stresses and the maximum shear stress at this point on the component (a) using analytical relationships and (b) by using Mohr's circles for strain and stress. The relevant material properties are: E = 80 x 10°N/m², v=0.3.

Question 1 The cylindrical pressure vessel shown has an inside diameter of 625 mm and a wall thickness of 5 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 70 GPa and a shear modulus of G-26.3 GPa. Two strain gages are mounted on the exterior surface of the cylinder at right angles to each other; however, the angle θ is not known. If the strains measured by the two gages are...
