MATLAB Introductory Learning Module

Created using MATLAB R2013a

Problem Specification

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

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

Solution Steps

The MATLAB solution is divided into the following steps:

• Step 1: Find Reactions RAR_A, RBR_B
• Step 2: Find σx σ_x for ri r_i = 1 cm
• Step 3: Plot σx σ_x vs. rir_i
• Step 4: Plot σx σ_x vs. rir_i: Take 2
• Step 5: Plot σx σ_x vs. rir_i: Take 3
• Step 6: Plot σ_x vs. r_i: Take 4
