AW250
\times 32.7
structural steel
E=200GPa
wideflange shape is loaded and supported as shown. A uniformly distributed load of
w=
18k(N)/(m)
is applied to the beam, causing the roller support at
B
to settle downward (i.e., displace downward) by
11mm
. Determine: (a) the reactions at supports
A,B
, and
C
. (b) the maximum bending stress
\sigma _(max)
in the beam. Assume
L_(AB)=3.8m,L_(BC)=4.9m
