Question 27 (5 points) The case for a desktop computer is made of steel that is 0.75 mm thick and has a plastic Poisson's ratio of 0.5. You know that the when the steel is unrestrained and placed in tension along one axis, the true strain in the axis perpendicular to the load is found to be -0.125 at failure. Estimate the minimum bending radius for the material. 1.32 mm 1.50 mm 1.87 mm 1.18 mm 1.65 mm

Step 1

Since the true strain in the axis perpendicular to the load is given as -0.125, we can use the equation for Poisson's ratio to find the true strain in the direction of the load. Poisson's ratio (ν) is defined as the ratio of the transverse strain (εt) to the Show more…
