A W530
\times 92
structural steel wide-flange shape
E=200GPa;I=554\times 10^(6)mm^(4)
is loaded and supported as shown. Determine: (a) the force and moment reactions at supports
A
and
C
(positive force is up, positive moment is counterclockwise). (b) the maximum bending stress
\sigma _(max )
in the beam. (c) the deflection
v_(B)
of the beam at
B
. Assume
L_(AB)=5.4m,L_(BC)=4.1m,P=141kN
