Plate

Mass = 84184.05 grams Volume = 31179276.94 cubic millimeters Surface area = 1916449.49 square millimeters Process: First, I sketched out half of the model (top half from the right view). Then, I extruded it using the Revolve Boss/Base tool. After this, I sketched out a single spoke directly in the middle of the model (above the hub, along the centerline) and extruded it up to the correct dimensions. Then, I used the circular pattern tool to create the rest of the nine spokes. Lastly, I configured the material and checked the mass.
