The blades of the portable fan generate a 1.8-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 25 lb acts at G. The moments are positive if counterclockwise, negative if clockwise. Assume a = 7.0 in., b = 1.5 in., c = 11.5 in., d = 4.5in., e = 2.0 in., and 0 = 19% Air flow 0 Answers: Due to thrust T Mo= Due to weight Mo= B The tolerance is ± 2%. i lb-in. lb-in.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
