Question
![For the following problem, a beam segment is shown. Assume Ax- 20 in. It is subjected to internal bending moment MA-42 kip-
in. at section A and internal bending moment MB = 33 kip-in. at section B. Also shown is a sketch of the cross-sectional dimensions
where b1= 7.0 in., d1= 2.50 in., b3 - 11.5 in., d3 = 2.00 in., b2 = 2.50 in., and d2-7.0 in. Consider area (2) of the beam segment
shown. For the problem:
(a) Sketch a side view of the beam segment and plot the distribution of bending stresses acting at sections A and B. Indicate the
magnitude of key bending stresses on the sketch.
(b) Determine the resultant forces acting in the x direction on area (2) at sections A and B and show these resultant forces on the
sketch.
(c) Is area (2) in equilibrium with respect to forces acting in thex direction? If not, determine the horizontal force required to
satisfy equilibrium for the specified area and show the location and direction of this force on the sketch.
