PROBLEM 1. The state of strain at a point on an experimental aircraft wing has components, ɛ. = 300 (10 ), ɛ, = -480 (10°) and yy = -750 (10*). Based on this information, a) Determine the equivalent in-plane strains on an element oriented at an angle of 60° clockwise from the original position and sketch the deformed element due to these strains within the x-y plane. b) Determine the in-plane principal strains and specify the orientation of the element and show how the strains deform the element within the x-y plane. c) Determine the maximum in-plane shear strain and average normal strain. Specify the orientation of the element and show how the strains deform the element within the x-y plane.
