Stress Due to Gravity

Created using ANSYS (Version Number)

Learning Goals

In this tutorial, you will learn to:

• (e.g.: Determine the displacements and stresses in a bike crank using 3D FEA capabilities in ANSYS Mechanical)
• (e.g.: Verify the finite-element results from ANSYS by refining the mesh and also comparing with hand calculations)

AIM 17.1

Problem Specification

Consider the geometry in the figure below.  The slender bar is 3 inches wide, 2 inches tall, and 50 inches long.  The large block on the end of the bar is 9 inches wide, 6 inches tall, and 6 inches long.  Both are made of structural steel with a Young’s modulous of 2.90075E+7 and a poisson’s ratio of .3.  The left end of the bar is fixed to a wall, and the geometry is subjected to standard earth gravity.  Calculate the maximum equivalent stress in the geometry.
