Question: Problem ( 1 0 0 points ) Consider the loaded beam shown. The cross section is given as W 1 6 x 7 7 .
Problem points Consider the loaded beam
shown. The cross section is given as Wx
wips
a Draw shear force diagram. Make sure to label axes p:
b Draw bending moment diagram. Make sure to label axes. p:
c Using the shear force and bending moment at the critical section p and the crosssection Wx
given, determine the bending stress and shear stress at various locations of the crosssection p
Note that points and are right below the flange and right above the web respectively.
d Using the bending stress and shear stress at locations determine the maximum absolute shear
stress at each location and in the overall crosssection.
e Knowing that ksi and ksi, select the most economical wideflange shape that should
be used to support the loading shown. Use MS excel to compare various crosssections from the App C Test
five to six different crosssections, and indicate the best one. p
