For the cantilever steel beam
(E=2\times 10^(8)kPa,I=120\times 10^(6)([[)mm(]])^(^())4)shown, use the double-integration method to determine the deflection at point A. Assume that
L=25
cm,P=40,000N, and
w=30,000(N)/(m). (A)
\delta _(A)=-20.5mm(B)
\delta _(A)=-26.1mm(C)
\delta _(A)=-8.71mm(D)
\delta _(A)=-14.8mm
