Angle of repose is equal to angle of friction.
a right angle is half of a straight angle
The purpose of measuring taper angle is to obtain taper angle
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
Propellers of a boat or an aeroplane are literally a continuous inclined planes on an axle. Screws could also be described as an inclined plane on an axle. The work being done, however, is quite different: propellers push or pull a fluid - air or water. As with simple inclined planes, the incline angle is proportional - the greater the slope, generally speaking, the greater the force required to move it through the fluid. Meaning that the propeller is shaped in the form of a Wing which produces lift when it moves through the air. They are not considered a flat plane. However, some wings can be a flat plate design and produce lift.

The angle of attack is an aerodynamic term which refers to the angle between the mean wing chord of the airfoil and the direction of airflow. This is different from the pitch angle of the aircraft in that the pitch angle refers to the aircrafts position in relation to the horizon, whereas angle of attack refers to the aircrafts angle in relation to airflow.
relation between critical angle and polarising angle?
Reverse pitch propellers allow the propeller blades to rotates to an angle that produced thrust in the opposite direction direction of flight. This allows propeller driven aircraft to stop faster than they would with braking alone.
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.

Thrust angle is the direction that the rear wheels are pointing in relation to the centerline of the vehicle.

The angle of reflection is equal to the angle of incidence, as stated by the law of reflection. This means that when a ray of light hits a surface and is reflected, the angle at which it bounces off is the same as the angle at which it originally struck.
There are two very general types of aircraft propellers: Fixed pitch and variable pitch propellers. Fixed pitch propellers are simply airfoils attached to the engine which spin and due to Bernoulli's principle, cause a lower pressure at the front of the propeller than they do at the back, thereby "pulling" the aircraft forward. They are controlled simply by a throttle lever which directly affects the RPM at which the propeller spins. Variable pitch propellers expand on this concept by allowing the pilot to vary the pitch at which the propeller is angled. By varying this, multiple angles of attack can be imposed on the propeller, meaning the pilot can select a certain angle to achieve greater climb performance, and then change the angle of the blade to achieve greater fuel efficiency. This type of propeller is controlled by two systems - the throttle, which controls the manifold pressure of the engine, and the "prop" control, which changes the angle of the propeller blade.
