MATLAB Introductory Learning Module
Created using MATLAB R2013a
Problem Specification
Consider the beam shown in the figure below. Using MATLAB,
a) Find the reactions RARA, RBRB
b) Find the bending stress σx σx at point O
c) Plot the variation of σx σx at point O as the inner radius of the tube is varied in the range 0.5 cm < ri ri < 1.5 cm
Beam figure

Solution Steps
The MATLAB solution is divided into the following steps:
- Step 1: Find Reactions RARA, RBRB
- Step 2: Find σx σx for ri ri = 1 cm
- Step 3: Plot σx σx vs. riri
- Step 4: Plot σx σx vs. riri: Take 2
- Step 5: Plot σx σx vs. riri: Take 3
- Step 6: Plot σx vs. ri: Take 4
