Step 1
Given ε1 = 720 με, ε2 = −180 με, ε3 = 120 με. The rosette is the standard rectangular 3-element one with gauges at θ1 = 0°, θ2 = 45°, θ3 = 90° (gauge 1 aligned with the x-axis). Show more…

The state of strain at the point on the pin leaf has components of $\epsilon_{x}=200\left(10^{-6}\right), \epsilon_{y}=180\left(10^{-6}\right),$ and $\gamma_{x y}=-300\left(10^{-6}\right) .$ Use the strain transformation equations and determine the equivalent in-plane strains on an element oriented at an angle of $\theta=60^{\circ}$ counterclockwise from the original position. Sketch the deformed element due to these strains within the $x-y$ plane.
