To become familiar with the general equations of plane strainused for determining in-plane principal strain, maximum in-planeshear strain, and average normal strain.
The state of strain at a point has components of ϵx=350.0×(10−6), ϵy=−200.0×(10−6), and γxy=150.0×(10−6).
Part A - Equivalent in-plane strains on the oriented element.Determine the equivalent in-plane strains on an element rotatedcounterclockwise at an angle of θ = 30.0 ∘
Part B - In-plane principal strains on the oriented element.Determine the in-plane principal strains on the orientedelement.
Part C - Maximum in-plane shear strain and average normal strainon the oriented element. Determine the maximum in-plane shearstrain and the average normal strain on the oriented element.
NOTE: This is my last attempt please I need a correct answer.Thank you in advance.
