The blades of the portable fan generate a 1.0-lb thrust T as shown. Compute the moment Mo of this force about the rear support point O. For comparison, determine the moment about O due to the weight of the motor-fan unit AB, whose weight of 7.7 lb acts at G. The moments are positive if counterclockwise, negative if clockwise. Assume a = 9.0 in., b = 1.5 in., c= 12.5 in., d=3.5in., e = 2.5 in., and 0 = 16⁰ Air flow
