The electric fan shown has the following specifications: The entire unit weighs W = 15 lb with the center of gravity shown. The fan produces a maximum thrust of T = 6 lb. The height h can be adjusted by the user between 24 and 48 in. The fan can be rotated to any horizontal position desired by the user. Specify the dimension h for a base having three equally spaced legs. In your work, assume that the weight of the legs is already included in the 15 lb weight of the unit. Your design should consider a reasonable degree of safety against overturning. Also make at least two suggestions for how the stability of the fan can be improved without increasing the weight W or increasing the dimension b.
