Question

Problem #3 (8 Points) fan shown blows air at 5000 f/min creating a reaction torce causing the fan to tip backwards. If the fan has a weight oF 22 Ibs, and a center of gravity at G, determine the smallest 15 ftG diameter d of its base so that it will not tip over weight of air is 0.076 lbs/A. HINT: A simple tip-over moment can be set aroun the base so that the fan air force times its perpen distance from this corner is balanced by the weight of the Jan (at the center of gravity) times its perpendicular distance 0.5 ft d the lower right-hand corner dicular of 4 ft to this corner.
