Consider the beam shown in the figure below. Using MATLAB,

a) Find the reactions R~A~R _A, R~B~R _B
b) Find the bending stress σ~x~ σ _x at point O
c) Plot the variation of σ~x~ σ _x at point O as the inner radius of the tube is varied in the range 0.5 cm < r~i~ r _i < 1.5 cm

This tutorial uses MATLAB version 7.1.

...

The MATLAB solution is divided into the following steps:

• Step 1: Find Reactions R~A~R _A, R~B~R _B
• Step 2: Find σ~x~ σ _x for r~i~ r _i = 1 cm
• Step 3: Plot σ~x~ σ _x vs. r~i~r _i
• Step 4: Plot σ~x~ σ _x vs. r~i~r _i: Take 2
• Step 5: Plot σ~x~ σ _x vs. r~i~r _i: Take 3
