# 2.2.5: Choose an Algorithm

![ Fig. 2.2.5.1: Deflection and stress-wise utilization of a cantilever beam with a point-load at its tip](/files/-M9XuWAYImH5oH8hzJ0R)

Karamba3D offers various options of analyzing a structural model. The **“Analyze”** component (see fig. 2.2.5.1) calculates the deformation and stresses of a model under external loads. The **“Deformation”**-slider in the submenu **“Display Scales”** of the **“ModelView”**-component allows you to scale the graphical output of the displacements. The default magnification factor is 50. In case the numeric range of the **“Deformation”**-slider does not fit it can be adapted.

{% hint style="info" %}
A double-click on the knob of the slider invokes a window for adapting the slider settings.
{% endhint %}

In order to get the numbers which correspond to the colors of the utilization output a **“Legend”**-component is used in fig. 2.2.5.1. Dividing the normal stress in a point of the cantilever by the strength of its material gives the stress-wise utilization output of the **“BeamView”**-component. Negative values correspond to compression, positive values to tension. Stress-wise utilization can be misleading: slender beams under axial compression buckle and thus collapse before the compressive stresses reach the material strength. The **“Utilization”**-component includes stability and should be used in such cases.
