The state of strain at the point on a boom of an hydraulic
Chapter 10, Problem 10-14(choose chapter or problem)
The state of strain at the point on a boom of an hydraulic engine crane has components of \(\epsilon_{x}=250\left(10^{-6}\right), \epsilon_{y}=300\left(10^{-6}\right), \gamma_{x y}=-180\left(10^{-6}\right)\). Use the strain transformation equations to determine (a) the in-plane principal strains and (b) the maximum in-plane shear strain and average normal strain. In each case, specify the orientation of the element and show how the strains deform the element within the x–y plane.
