STRUCTURAL ANALYSIS 10TH EDITION
2026 COMPLETE SOLUTION MANUAL
QUESTIONS AND ANSWERS GRADED A+
⩥ What should you be able to find for determinate beams before this
lecture?
Answer: The external reactions, including those with internal moment
releases.
⩥ What graphical approach is used in this course to draw shear and
moment diagrams?
Answer: The graphical approach to draw actual shear and moment
diagrams.
⩥ What concept was introduced in Lecture 12 that is further explored in
Lecture 13?
Answer: The superposition of cantilevered parts.
⩥ What are the common loadings encountered in structural analysis of
cantilevers?
Answer: Concentrated moments, concentrated loads, and uniform
distributed loads.
,⩥ What is the internal bending moment equation for a cantilever with a
concentrated moment Mo?
Answer: M(x) = Mo.
⩥ What is the internal bending moment equation for a cantilever with a
concentrated load P?
Answer: M(x) = Px.
⩥ What is the internal bending moment equation for a cantilever with a
uniform distributed load (UDL) w?
Answer: M(x) = (wo/2)x^2 for constant UDL.
⩥ What is the internal bending moment equation for a cantilever with a
linearly increasing load?
Answer: M(x) = (wo/(6d))x^3.
⩥ What is the significance of the direction of loading on a cantilever?
Answer: It produces positive internal moments, but can be flipped to
yield negative moments.
⩥ What should students verify when drawing moment diagrams by
cantilevered parts?
Answer: That the results make sense for the beam loading and boundary
conditions.
,⩥ What is the first example of loading discussed in Lecture 13?
Answer: Simple Span with Uniform Distributed Load (UDL).

Answer: 16 ft.
⩥ What are the lengths of the segments in the Simple Overhang
example?
Answer: 12 ft and 6 ft.
⩥ What is the purpose of moment diagrams in structural analysis?
, Answer: To visualize internal moments and ensure structural integrity.
⩥ What future courses will revisit the concepts of moment diagrams and
superposition?
Answer: CE 382 and CE 383.
⩥ What is the role of moment releases in beams?
Answer: They are essential for the force method of indeterminate
analysis.
⩥ What should students do after finding reactions in beam loading
examples?
Answer: Draw the actual moment diagram and then the moment diagram
by cantilevered parts.
⩥ What is the primary focus of Lecture 12 in CE 381?
Answer: Drawing bending moment diagrams by superposition of simple
parts, particularly cantilevers.
⩥ What should students be able to do before attending Lecture 12?
Answer: Solve for the external reactions of simple beams and find the
internal bending moment function, M(x), for a determinate beam.
