The blades of the portable fan generate a 1.2-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 6.7 lb acts at G. The moments are positive if counterclockwise, negative if clockwise. Assume a = 8.0 in., b = 2.0 in., c = 10.0 in., d = 3.5in., e = 2.5 in., and 0 = 17% Air flow T d Answers: Due to thrust T Mo= 2 Due to weight Mo = i i B lb-in. lb-in.
