Calculate the required deflections using Moment$-$Area method:

$14-38$ Calculate the deflection at the free end of the Douglas fir beam shown in Fig. P$14-38.$ The cross section has a moment of inertia of $1\mathrm{.}2{10}^{6}m{m}^4.$

$14-47$ The $6061-$T$6$ aluminum beam shown in Fig. P$14-47$ has a cross section with a moment of inertia of $375{10}^{5}m{m}^4.$ Calculate the maximum deflection in the beam.

$14-44$ Find the deflection at the free end of the W $410100$ structural$-$steel beam shown in Fig. P$14-44.$

$14-49$ Calculate the maximum deflection for the structural$-$steel w$530$x$10$ beam shown in Fig. P$14-49.$
