1. When a 150 pound uniformly distributed load is applied to the bracket, the factor of safety with regard to stresses must be at least 2.0. The factor of safety can be calculated by dividing the material yield strength by the maximum von Mises stress (Equivalent Stress) in the bracket. The load is applied along the bottom horizontal surface, as shown in Figure1. Note that the total load for the entire structure must equal 150 ๐๐๐ . In Workbench, the load can be applied as pressure or a force. Be sure your model appropriately makes use of symmetry, and the result of the applied loading in your analysis is consistent with 150 ๐๐๐ total loads applied to the entire structure. Since your taking advantage of symmetry, the load applied to the half that you model should be 75 ๐๐๐ .

2. Under the loading outlined in Item 1 above, the vertical direction ( y-direction) deflection for any point on the bottom edge on which the load is applied cannot exceed 0.015โ. Suppose the model is set up according to the coordinate directions shown in Figure 1, based on the loading. In that case, the deflections along the bottom edge will be in the negative y-direction, so the maximum absolute value of the y-direction deflection for any node along the bottom surface must not exceed 0.015โ.
