9. (25 points) Consider a beam with the following beam
cross section being being around the x-axis. A downward
10,000 lb force is applied to the right end end of the beam
and the beam is fixed at the left end. The beam is 36"
long. The beam is Al (E = 10,200,000 psi)
Fill in the following table:
item
location of the neutral axis
moment of inertia (use both methods and
show work)
The term \"Section modulus\" refers to the
moment of inertia of a beam divided by 'c',
S=I/c. This simplifies the relationship between
bending moment and stress from (M = \sigma I/c) to
M = \sigma S. Calculate the section modulus of the
above beam.
determine the max stress in the beam
Determine y(x)
determine the max deflection of the beam
