With the strain gauge set shown in the attached picture, E = 290 , B = -180 and = &c = -600 have been measured from the surface of the steel piece in the of resistance. It is assumed that the load that produced the strains does not occur on the surface to which the strain strips are glued. In addition, it is known that the material the yield strength is R = 235 MPa, elastic modulus E = 195 GPa and Poisson's constant = 0.26 and the material is isotropic. Specify a) the component matrix of the strain tensor of the small strains of the deformation at the measurement point, [] = b) stress component matrix in the image coordinate system, [0] = u and Overt = c) Determine the reference stress according to the von Mises yield condition at the measurement point, MPa and MPa. nVvEH = d) certainty of the measurement point according to the sales ratio von Mises, 2 45 B A X1
