Answers:

How do you make a two material airplane?

Usually via a drive shaft that runs from the main gearbox to the tail rotor although some helicopters use a "v-belt" train. Some helicopters even use the jet exhaust of the gas turbine engine to produce anti-torque thrust.

I'm an A/C aircraft mechanic.i want to get an FAA license,anyone help me where or to find the review centre?

The tail rotor also known as the anti-torque rotor, is used to stop the helicopter from rotating in the opposite direction of the main blades. The foot pedals in the helicopter adjusts the angle of the tail rotor blades to provide more or less thrust. "Pedal turns" use this feature to tun the helicpter in hovering flight.

what size is the engine that powers a tomahawk cruise missile? length? diameter?

Helicopters like the Chinook with two main rotors and others that have two coaxial main rotors have the two main rotors turn in opposite directions to negate the torque effect.

what are the numbers of passenger in boeing747?

Drive shafts that run from the main transmission (below the main rotor) to the tail and through gearboxes. One gearbox if the rotor is on the same horizontal plane as the tail boom (Bell 206), and two if it is elevated to the top of the stabilizer (Huey, Blackhawk, Apache). The speed is geared up by the gearbox(s) and transmission, it has to spin much faster than the main rotor.
