E=200GPawideflange 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
Bto 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. Answers: (a)
