Please read the following instructions carefully:
-
Late submission
will be penalized. (minus 10 points/day). -
Individual work
. Plagiarism in your solution will be treated as academic dishonesty. -
Submit ONE
report in pdf and FOUR
.db files (ANSYS models) through the assignment dropbox. Total: 4 Questions (40 points)
Question 1 (10 points)
Use ANSYS to determine the shear force (SF) and bending moment (BM) diagrams of the following beam shown in figure 1. For this question:
-
Use a minimum of 30 elements for the total beam elements. -
Use the values obtained in ANSYS, and plot the SF and BM diagrams (e.g., by using Excel). Your answer must also include:
-
Assumptions, element type used, material properties. -
Diagram of the model showing load and boundary condition. -
Reactions. -
Table of element shear force and bending moment. -
The shear force and moment diagrams (x-axis must be length of beam in m).
