Last week, I created #14967 for implementation of plotting methods. Soon after pushing my commits, many of the jobs failed on Travis. It was strange as I was not able to reciprocate the errors locally.

This week I started working on implementing methods to plot Shear force, bending moment, slope and deflection diagrams. #14967 was created for it.

I started implementing Beam_3d class which can be used to find Shear force, Bending moment, Slope, Deflection and other few things for the Beam object. PR #14883 was created for this.

This week I mainly focused on finding and solving a bug due to which continuum_mechanics gave ValueError on using units with the quantities passed. Initially, I created #14856, which included a workaround in the Beam class itself to handle that error. But Arihant suggested opening a separate PR as the error was occurring due to a bug in the separate module.
