# 3D Finite-Element Analysis of a Bike Crank

Created using ANSYS AIM 17.1

## Learning Goals

In this tutorial, you will learn to:

Determine the displacements and stresses in a bike crank using 3D FEA capabilities in ANSYS AIM

Verify the finite-element results from ANSYS AIM by refining the mesh and also comparing with hand calculations

## Problem Specification

Consider the following bike crank model.

To orient ourselves, the following figure shows the location of a similar bike crank mounted on a bicycle.

**Material properties**: The bicycle crank's material is aluminum 6061-t6. The Young's modulus is 10,000 ksi, and the Poisson's Ratio is .33.

**Boundary conditions**: Apply a load of 100 lbf in the y-direction on the right hole surface and fix the 3 left hole surfaces as shown below. Note that this is an approximation of the actual loads and constraints on the bike crank.

Using ANSYS AIM, determine the following:
