Chapter 14, Problem 9RP

The 60° strain rosette is mounted on a beam. The following readings are obtained for each gage: ${ϵ}_a=600\left({10}^{-6}\right)$, ${ϵ}_b=-700\left({10}^{-6}\right)$, and ${ϵ}_c=350\left({10}^{-6}\right)$. Determine (a) the in-plane principal strains and (b) the maximum in-plane shear strain and average normal strain. In each case show the deformed element due to these strains.
