h3. Total Deformation

The first back-of-the envelope calculation that we will make is for the total deformation of the crank under the specified applied load. A list of different cantilevered beam loading cases along with their closed-form maximum deflections formulas can be accessed on this link. Because our beam is loaded at the second hole instead of at the tip, our loading is best represented by the case 2 presented (i.e for a cantilevered beam with a concentrated load, P, at any point). The appropriate formula for the maximum deflection is therefore
{latex}
\begin{equation*}
\delta_{max} = -\frac{Pa^{2}}{6EI}(3L-a)
\end{equation*}
{latex}

where P is the load, L is the distance from the support to the load, E is Young's Modulus and I is the moment of inertia.

h3.

The following video shows how to launch ANSYS Workbench and choose the appropriate analysis system (which, under the hood, sets the governing equations that one will be solving). The video also shows how to add a new material to the material list for this project. We'll later assign our material to the model in the [Physics Setup|Bike Crank - Physics Setup] step.
