Hey guys, Im in the middle of a project and need help with the base for it. I have to develop a base for a rectangle 3 feet high by 2 feet wide by 6 inches deep. The front of the rectangle is 1 pound heavier than the back and will stand 2 feet off the ground. The base must be able to make the rectangle stay in place while having a object weighing 5.5 ounces coming at a straight on downward angle at a velocity of up to 95 mph. Also I need another base to withstand a 6.8 ounce object coming from a straight on upward angle at 72 mph. Could someone help me out with the most stable design for both scenarios?
