1. Show whether natural strains are additive or not. Ditto for conventional strains. 2. Find the principal stresses, the orientation of the principal axes of stress, and the maximum shear stress when 8 xx = 140 MN/m² 8 yy= 20 MN/m² Syy = 20 MN/m² 3 xy = -60 MN/m² 3. What is the diameter change of a 50-ft spherical tank made of ½ "steel plate due to internal pressure of 100 psi? Assume that the tank may be considered as "thin-walled" and that the steel remains elastic and has the properties Elastic modulus Poisson's ratio Internal pressure Thickness steel Diameter = 30,000,000 psi 0.3 100 psi ½½/2" 50 ft
