The 45° strain rosette is mounted on a surface of the bracket . The bracket is made from steel with Esteel = 120 GPa and poison ratio, v = 0.28. The following readings are obtained for each gauge under loadings:
Ɛa = [ X+Y ] (10-6)
Ɛb = -200(10-6)
Ɛc = -180(10-6)
x=100, y=100
(a) Estimate the in-plane principal strains and the angle associated with the principal strains, and
(b) Calculate the principal stress associated with the principal strains in (a).
