The strain rosette shown in Figures P13.41 was used to obtain normal strain data at a point on the free surface of a machine part.
(a) Determine the strain components at the point.
(b) Determine the principal strains and the maximum in-plane shear strain at the point.
(c) Draw a sketch showing the angle, the principal strain deformations, and the maximum in-plane shear strain distortions.
(d) Determine the magnitude of the absolute maximum shear strain.
