2. A length of angle iron modeled using Abaqus. The Abaqus DAT
file, ODB file, and CAEfile for this model are available at
S:\ENS\Mechanical Engineering\Daily\FEA\Exam2\.Using those files
(and your own understanding of mechanics), please answer the
followingquestions:
a) What is the angle of inclination if zero is vertical?
b) What kind of element was used?
c) What is the cross-sectional area of the angle iron?
d) What is the cross-sectional moment about the global z axis at
the centroid?
e) Where are boundary conditions applied (please provide lengths
along the neutral axis)?
f) Where are loads applied, what are their magnitudes, and what
are their directions?
g) Is the angle iron in tension or compression?
h) How heavy is the length of angle iron being modeled?
i) What is the maximum bending deflection of the beam? (Hint:
Redraw the deformedshape along a straight line and determine the
deviation from that line.)
j) If the yield strength is 36000 units, will the beam
experience yielding? What is themaximum stress in this beam?
k) BONUS: What are the frequencies of the first two mode shapes
of this beam?
