Each main wheel weighs 753 pounds, nose wheel weighs 22 pounds, distance between nose wheel and main wheels is 87.5 inches, nose wheel location is +9.875 inches from the datum, with 1 gallon of hydraulic fluid at –21 inches included in the aircraft weight. EWCG is _________________A rotating shaft carrier flywheel which overhangs on the bearing as a cantilever. If this flywheel weight is increased to double of its original weight, the whirling speed will increase by _____ / decrease by ____ / will remain constantWords: Assembly, Axle, Banjo, Carrier, Contaminants, Heavy-duty, HousingThe removable ________________ axle housing is open on the front side. Because it resembles a ________________, it isoften called a banjo ________________. The backside of the housing is closed to seal out dirt and ________________and keep in the lubricant. The gears are mounted in a carrier ________________ that can be removed as a unit from the________________ housing. Removable carrier axle housings are most commonly used today on trucks and other________________ vehicles.
- The stresses in a powered screw include: ___________________________. True or False with explanation For both shaft design and spring design, the running frequency should be at least two times lower than the first mode of natural frequency. True_ False__. The major stress in a spring comes from the direct shear. True_ False__. The natural frequency of a spring can be reduced by reducing the weight of the wire. True_ False__. Considering the contact fatigue of a gear, the wear factor should be higher than the gear factor. True_ False__. The pitch of the body coil can be calculated from the number of active coils and the critical length of the spring. True_ False__A significant disadvantage of using a flywheel with a reduced moment of inertia would most likely be: The flywheel would decrease in speed between power strokes of the piston The engine would be more difficult to start The engine as a whole would weight less The flywheel would be subject to higher stressesIce skating is an example of ______________ Select one: No friction Static friction Sliding friction Dynamic friction
