For the beam properties given below:

l$=4$m$,$E$=70$GPa

h$=0\mathrm{.}346$m$,$

u $=0\mathrm{.}35$

w$=0\mathrm{.}346$m$,\backslash$rho $=2\mathrm{.}7$E$3$k$($g$)/($m$^(3))$

$($a$)$ Use ANSYS to determine the first six frequencies of vibration in the xy plane

for the beam if it is cantilever $($fixed$-$free$).$ Print a graph of the beam displace$-$

ment for all $6$ six frequencies.

$($b$)$ Repeat the analysis for the beam vibrating in the xy$-$plane if it is fixed at both

ends $($fixed$-$fixed$).$

$($c$)$ Comment on the effect of the boundary conditions on the vibrational behavior

of the beam.
