Question Description

Please submit a published pdf code from Matlab

For the dimensions of the beam, make sure you don't have ";" at the point where you evaluate the size so that the results gets printed.

e.g.,

h=4*b

rather than

h=4*b;

These are the notes from the professor about the homework. You will find the questions attached.

ME 526 Homework 9 1) Plot the N, V, and M diagrams for the beam. 2) If the cross sectional area of the beam is a rectangle with height = 4 times the width, what should be the dimensions of the beam so that the axial stress does not exceed 10 MPa at any point of the beam? Use these dimensions for the rest of the assignment. 3) Plot the maximum axial stress as a function of the length of the beam. 4) For the location with the maximum axial stress, plot the axial stress as a function of the vertical distance from the neutral plane. 5) Make a plot of the maximum shear stress as a function of the length of the beam. 6) For the location with the highest shear stress, make a plot of the shear stress vs. distance from the neutral axis. ...

2. If the cross sectional area of the beam is a rectangle with height = 4 times the width, what
should be the dimensions of the beam so that the axial stress does not exceed 10 MPa at any
point of the beam? Use these dimensions for the rest of the assignment.

Simply Supported Beam
Type 1 for point load, Type 2 for udl

Left support Reaction = 105 kN
Left support Reaction = 15 kN
Maximum bending moment = 275.625 kNm
L = 6
Dimension = 144
axial_stress = 10

3) Plot the maximum axial stress as a function of the length of the beam.
