So not to vibrate and put stress on bearings and seals.

Propellers are measured in stations. This is done by first finding the propeller station number where the angle measurements are taken. Stations are measured in inches from the center of the propeller hub. As an example; propeller station 35 would be 35 inches from the center of the hub. The propeller maintenance manual and/or the Type Certificate Data Sheet for the specific propeller will provide the station number. Once you have located the proper station a propeller protractor is used to measure the angle. The protractor must first be "zeroed" (normally at the hub). Then the angle will be checked on the "Face" of the blade (this is the side that "faces" the pilot when sitting in the pilot seat). This must be done on each blade of the propeller to ensure they are all the same (or within limitations set by the manufacturer).
if the net force is balanced then it has to be zero
They commonly have one rotor and one propeller for stability .
1) keyed propeller and 2) keyless propeller................... they have further classificaton 1.fixed pitch propeller 2.controllable pitch propeller 3.directional pitch propeller
How do you build a propeller
A boat moves at a constant velocity if the force provided by the propeller exactly balances the resistive forces such as drag and friction acting on the boat. Once the forces are balanced, the boat will continue moving at a constant velocity as long as the propeller keeps applying the same force.
It's not! Any number of blades are ok as long as the blades are equally spaced apart and its balanced.
A propeller airplane is, simply put, any airplane which uses a propeller for propulsion.
You must get the Brown Propeller Hat from the Gadget Room in the HQ.
In a balanced nuclear equation, the sum of the mass numbers on the right must equal the sum on the left
A propeller is a rotating wing.
