10-27. The strain rosette is attached at the point on the surface of the pump. Due to the loading, the strain gauges give a reading of P a = −250(10 −6 ), P b = 300(10 −6 ), and P c = −200(10 −6 ). Determine ( a) the in-plane principal strains, and ( b) the maximum in-plane shear strain. Specify the orientation of each element that has these states of strain with respect to the x axis. | |
