Problem: Model a cantilevered beam using plate elements subjected to a constant tip loading. The plate elements will undergo bending. With plate material: Aluminum with E = 10 x 10^6 psi and n =0.3. With a load on tip of plate = 8 lbf. Finally, display the von Mises stress and the deformed shape of the plate model.
