Question:
General instruction of the activity:
Consider the following image of a W-section beam:
Determine:
a) The distance "a" for which the maximum absolute value of the bending moment on the beam is
as small as possible. (30 points)
b) Maximum normal stress due to bending (30 pts.)
c) Suppose there is an axial stress in X normal to the 3KN section, what kind of bending
would happen to be (10 points)
d) With this new hypothesis, calculate the maximum resistance of the beam. (30 points)
