MATLAB Intro Problem Specification

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

This tutorial uses MATLAB version 7.1.

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
