Current Attempt in Progress
The blades of the portable fan generate a 1.7-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 15.7 lb acts at G. The
moments are positive if counterclockwise, negative if clockwise.
Assume a = 7.5 in., b = 2.5 in., c = 13.0 in., d = 3.5in., e = 1.5 in., and 0 = 15%
