The (45^{circ}) strain rosette is mounted on the link of the backhoe. The following readings are obtained

Question:

The $45^{\circ}$ strain rosette is mounted on the link of the backhoe. The following readings are obtained from each gauge: $\epsilon_{a}=650\left(10^{-6}\right), \epsilon_{b}=-300\left(10^{-6}\right), \epsilon_{c}=480\left(10^{-6}\right)$. Determine

(a) the principal strains and

(b) the maximum in-plane shear strain and associated average normal strain.
