using Mohr’s circle.

10−6. The state of strain at a point on the bracket has components of ε_x = 150(10⁻⁶), ε_y = 200(10⁻⁶), γ_xy = −700(10⁻⁶). Use the strain transformation equations and determine the equivalent in-plane strains on an element oriented at an angle of θ = 60° counterclockwise from the original position. Sketch the deformed element within the x–y plane due to these strains.

10−7. Solve Prob.10-6 for an element oriented θ = 30° clockwise.
