-   :alt: A diagram showing a simplified representation of a structure with three rigid beams connected by what appear to be pivots or joints, indicated by circles, aligned vertically. The uppermost joint is labeled "w/2," and the lower two are each labeled "w," suggesting a distribution of forces or weights. The base of the structure is attached to a surface indicated by shaded diagonal lines, which may represent it being fixed or anchored. The words "Rigid beams" are noted to the right side of the structure, emphasizing its construction. The background is solid black, and the diagram is depicted in white lines and text for contrast.

    :alt: A screenshot showing a software interface with a bar chart and a data table. The bar chart is labeled "Frequency %" on the y-axis and "repair cost" on the x-axis, with bars representing different frequencies at varying repair cost intervals. The data table beneath the chart lists numerical values across columns with headers such as "repair cost," "pair time - paral," "air time - sequer," "collapsed?" and "irreparable?" The interface also includes a sidebar with various menu options like UQ, GI, SIM, EVT, FEM, RV, DL, and RES highlighted in turquoise.

-In the **Data** tab of the **RES** panel, we are presented with both a graphical plot and a tabular listing of the data. By left- and right-clicking on the individual columns the plot axis changes (left mouse click controls vertical axis, right mouse click the horizontal axis). If a singular column of the tabular data is selected with both right and left mouse buttons, a frequency and CDF plot will be displayed.
