M20 Concept Question 1 Strain gauges are applied to a block of linear elastic isotropic material with Young's modulus E = 100 GPa and Poisson's ratio n = 0.1. The block is loaded and strains: e x = 100 µ e , e y = -1000µ e , e z = 100µ e are recorded. The applied loading most simply/accurately corresponds to: 1. s x = 10 MPa , y =- 100 MPa , z = 10 MPa , 2. x =- 10 MPa , y =+ 100 MPa , z =- 10 MPa , 3. x = 0, y =+ 100 MPa , z = 0, x = (l + 2 m)e x + le y + le z , 4. s= (l+ 2 y + le x + le z , y z = (l + 2 z + le x + le y 5. x = 0, y =- 100 MPa , z = 0, 6. Some other expression 7. DNK/DNU
