Homework
#10
Due start of class on Wednesday, April 13, 2011
The purpose of homework assignments is for students to gain further understanding of classroom
principles through application to practical problems.
Although discussion of assignments between
students is permitted, the solution must represent your own efforts and understanding of the problem.
Blatant copies of the solutions will not be accepted, and repeated evidence of copying will lead to failure of
the course.

Problem 1
Please do part a. of Problem 5.54 in the textbook.
(You do not need to do part b
described in the textbook, but you might consider how its solution would differ from
part b.)
A simply supported wood beam AB with span length L = 4 m carries a uniform load of
intensity q = 5.8 kN/m (see figure).

Please do Problem 5.519 in the textbook.
A beam ABC with an overhang from B to C supports a uniform load of 200 lb/ft
throughout its length (see figure).
The beam is a channel section with dimensions as
shown in the figure.
The moment of inertia about the z axis (the neutral axis) equals
