The beam shown below carries point and linearly distributed loads and is supported by a pin on the left and a roller on the right.
The beam shown below carries point and linearly distributed loads and is supported by a pin on
the left and a roller on the right. Note that rollers can be assumed to react to either tensile or
compressive loads.
a For each beam, draw all necessary freebody diagrams using the method of sections and
find functions for the internal shear force and bending moment due to the
external forces where is a horizontal coordinate along the length of each beam, measured
from the left end of each beam, as shown in the figure. Your expressions must allow to
obtain internal reactions for where is the length of each beam. Make sure you
use the numerical values of the reactions at the supports to get your expressions. Note that
k stands for "kip" lbs in the labels for the point loads and distributed loads.
b Plot and using the expressions you obtained above using a computer program.
You will lose points if handdrawn plots are submitted.
