Chapter 10.3, Problem 10.2P

The state of strain at the point on the arm has components of ε_x = 200 (10⁻⁶), ε_y = −300 (10⁻⁶), and γ_xy = 400(10⁻⁶). Use the strain transformation equations to determine the equivalent in-plane strains on an element oriented at an angle of 30° counterclockwise from the original position, Sketch the deformed element due to these strains within the x–y plane.
