Hitch Pivot

Material is Cobalt. Density = 0.01 grams per cubic millimeter Mass = 48008.37 grams Volume = 5394199.26 cubic millimeters Surface area = 242568.33 square millimeters HP1: I sketched out the front of the part by starting with a 45 diameter circle in the middle and then measure down 45mm from the center and create a 120mm line to the left, connecting to a line going 50mm up. Continue the 120mm long line to be 300mm long and then create a line at 30 degree angle, 45mm long. Create a 40mm long line connecting to the angular line and then, create another line going to the left at a 30 degree angle and 45mm long. Finally, just create a horizontal line about 170mm and connect a 2 point arc with a radius of 280. Then, just extruded the shape by 200mm. HP2: Density = 0.01 grams per cubic millimeter Mass = 23495.32 grams Volume = 2639924.01 cubic millimeters Surface area = 195446.34 square millimeters I completed the same steps as for HP1 but then I created a sketch on top of the part 12.5mm away from edges, 75mm to the right, 25mm down, 150mm to the right and 125mm down. The same is on the bottom and then create a 45 degree angle, 50mm away from the drawing on the left. Then extrude it all the way. Then on the right side, create a 10mm radius circle in the middle and cut extrude it all the way. HP3: Density = 0.01 grams per cubic millimeter Mass = 18252.46 grams Volume = 2050838.72 cubic millimeters Surface area = 210429.73 square millimeters I used HP2 and then just created an offset and cut extruded one of the sides.
