The list of problems that were listed in the previous blog post have been sorted and the respective changes have been pushed.

• The properties reaction_forces and internal_forces were added for each support and each member respectively.
• The method change_label was added so that the user can change the label of a node or a member without having to delete it.
• Added a different image for the truss example as the images were added from Russell C. Hibbeler - Mechanics of Materials-Pearson Education (Prentice Hall) and hence could be copyrighted. Out of the two images added, the first image containing examples of multiple trusses was removed and the second image was replaced by the one below.

This truss was generated using this site.

Along with these above, a few minor changes were also made.

As per the timeline given in my GSoC Proposal, I was supposed to get started with the work of the solve method to solve for all the reaction forces and the internal forces of the Truss. With my current PR still open, I have started work on the solve method separately. As I intend to open a different PR for this method, I will be waiting for my currently open PR #23629 to be merged. After that I will open a different PR to push changes related to the solve method.

On the open PR, a few more changes are to be made:

• To have different change_label functions for nodes and members to deal with nodes and members having the same labels.
• When a support is added at a node, a load should be added 'R_'+str(location)+'_x/y' at the respective node instead of adding a zero force to _reaction_loads. The forces should be added to the dictionary only after calling the solve method and should be empty otherwise.
• Follow the same naming scheme as the Beam module and hence some methods like add_support and reaction_forces should be changed to apply_support and reaction_loads.

Hence, I will be making changes and try to get my first PR get merged as soon as possible and at the same time work on the solve method separately.
