MATLAB Introductory Learning Module

Created using MATLAB R2013a

Problem Specification

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

a) Find the reactions R_A, R_B
b) Find the bending stress σ_x at point O
c) Plot the variation of σ_x at point O as the inner radius of the tube is varied in the range 0.5 cm < r_i < 1.5 cm

Solution Steps

The MATLAB solution is divided into the following steps:

• Step 1: Find Reactions R_A, R_B
• Step 2: Find σ_x for r_i = 1 cm
• Step 3: Plot σ_x vs. r_i
• Step 4: Plot σ_x vs. r_i: Take 2
• Step 5: Plot σ_x vs. r_i: Take 3
• Step 6: Plot σ_x vs. r_i: Take 4
