1) For the beam with loadings shown in the figure , select the best design

with least displacement among the given cross sections for the given

loading. Consider E=205 Gpa.

2) Among the three sections shown in the above figure, for the one which

has the highest displacement carry out 3D modal analysis-Cantilever

beam condition, extracting 10 modes. Length = 350mm. Consider

=7800 kg/m3.

3) For the given bracket shown in the figure below, consider E=200 GPa,

=0.3, 1 inch =25.4mm. Left end of the bracket completely constrained

and pressure is applied only on right side of the hole shown in the figure

below. P = 3KN/m2. Determine the following.
