B$5(30$ pts$,$ Text $6\mathrm{.}17,$ modified$)$: For the configuration shown in Figure below, assume plane stress approximation and determine the deflection at the point of load application. Assume one point load of $240$ N acting vertically. $t=1\mathrm{.}2mm,E=60$GPA,$v=0\mathrm{.}3$

Solve the problem longhand for one element $($Mathcad or Matlab is OK$).$ Use the "plane stress CST element" handout.

Perform MARC simulation with one element. Include one graph with boundary conditions and one graph containing the deformed&original shape and the $y-$component of displacement.

Refine your MARC mesh by using Subdivide and Sweep commands $($choose parameters $661$ for divisions$).$ Again, produce $($and submit$)$ the deformed shape and $y-$displacements. Comment on results.
