The 60° strain rosette is mounted on a beam. The following readings are obtained for each gauge: ϵa = 600(10−6), ϵb = −700(10−6), and ϵc = 350(10−6). 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.
