Chapter 10.3, Problem 10.4P

The state of strain at the point on the pin leaf has components of ε_x = 200(10⁻⁶), ε_y = 180(10⁻⁶), and γ_xy = −300(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 due to these strains within the x-y plane.

*10−4. Solve Prob.10-3 for an element oriented θ = 30° clockwise.
