The modulus of elasticity of the material is E = 10,000 ksi and Poisson’s ratio is 0.25. The maximum shear strain is1100 micro1300 micro1900 micro1800 microNone of the above8. A point in plane stress has the Mohr circle for strain shown in Figure (h). The modulus of elasticity of the material is E = 10,000 ksi and Poisson’s ratio is 0.25. The maximum shear strain is1100 micro1300 micro1900 micro1800 microNone of the above9. In plane strain there are two principal strains, but in plane stress there are three principal strains.TrueFalse10. The principal coordinate axis for stresses and strains is always the same, irrespective of the stress–strain relationship.TrueFalseDo you have any comments or suggestions?
