Solve for 2-2

2-1 Find the maximum stress in the aluminum plate shown below. Convert the 12 kN concentrated force into an equivalent pressure applied to the edge. Use tabulated stress concentration factors to independently calculate the maximum stress. Compare the two results by determining the percent difference in the two answers.

2-2 Find the maximum stress for the plate from 2-1 if the hole is located halfway between the centerline and top edge as shown. You will now need to model half of the plate instead of just one quarter and properly restrain vertical rigid body motion. One way to do this is to fix one keypoint along the centerline for UY displacement.
