Introduction:

            The purpose of this project is to design three transmission shafts that will power a deep water well mud extractor. The engineers would have to know the weight of the load being lifted, as well as power input required by each motor to be able to safely escort the load to its designated location. The critical specification in this project is the diameter of the transmission shafts as they are critical in allowing the mud extractor the ability to lift its load with precision and safety.  Given certain specifications about the project is a start, however the engineers will have to combine their knowledge of mechanics of materials, machine design, and physics to be able to compute the necessary component specifications. The engineers had to select some factors of their own: the stress yield point was chosen as 350 MPA, the material was chosen as steel, the factor of safety was 2, the shock under bending factor was 1, the shock under torsion factor was 1, the endurance limit was selected as 124 MPA, and the max shear stress was selected as 175 MPA.
