#10 The 45 strain rosette is mounted on a machine element. The following readings are E obtained from each gage: a = -450(106), = -600 (10-6), ce =-300(10-6). Determine (a) the in- plane principal strains and (b) the maximum in-plane shear strain and associated average normal strain. In each case show the deformed element due to these strains.
