I chose to base my project on this question since I thought it was a realistic question to try and create a physical representation of.
This is my adapted question for my project and the solution.
These photos show the design process and the different solutions I thought of.
This diagram highlights the different pieces necessary for the project to work. The plate on the back of the apparatus is used as a place to put something like a textbook in order to make sure the model stays in place. The string is attached to the weight and is held in place by the screw which attaches it to the model and by design allows the string to be easily interchanged.
This photo shows how the model can be used to find the angle of the string.
