$2)$ A schematic of a bracket structure is shown in Figure $3.$ You are asked to determine the stress$/$strain distribution throughout the structure. Select a suitable finite element to mesh the geometry, assuming the structure to be "thin" in the out$-$of$-$plane direction. Sketch the mesh with appropriate mesh density in various parts of the structure using symmetry wherever possible, and identify the boundary conditions for the following cases:

i$.$ The material is isotropic. The load $\backslash ($ P $\backslash )$ is applied vertically downwards as shown.

ii$.$ The material is orthotropic. The load $\backslash ($ P $\backslash )$ is applied vertically downwards.

iii. The material is isotropic. The load is $\backslash ($ P $\backslash )$ is applied horizontally.
