Because the load taking capacity of hollow shaft is more as the load per unit area is lesser due to the lesser cross sectional area.
There are many, many examples. Generally, rotating shafts are used to transmit power from a producer to a user device. A few examples: Drive shaft in an automobile- transmits power from the engine to the wheels. Propeller shaft in a ship- transmits power form the engine to the propeller. Pump shaft- transmits power from a motor to the pump impeller. Rotating shafts are all over the place. You can find dozens of examples in the typical appliances in any typical home.
With a generator mounted on the "turbine". The propeller spins the generator shaft.
may i know the other term of propeller blade particular in ship propeller There is no alternative term for "propeller blade", but the entire prop is sometimes called a screw.
A uni-rotating propeller is one that can go around in both directions. This type of propeller typically will do different things depending on which direction it is going.
Two types of transmission shafts commonly used in engineering systems are the propeller shaft, which transfers power from the engine to the wheels in vehicles, and the cardan shaft, often used in heavy machinery for transmitting torque at varying angles. For couplings, flexible couplings are used to connect shafts while accommodating misalignment, and rigid couplings provide a more fixed connection. In terms of brakes, disc brakes are widely used in vehicles for their effective stopping power, while drum brakes are often found in older vehicles and some industrial applications. As for clutches, friction clutches are commonly used in manual transmissions to engage and disengage power, while electromagnetic clutches provide a quick and reliable means to engage and disengage loads in various machinery.
why propeller shaft are made hollow
To reduce weight and for good heat disposal.
automobile propeller shaft material
The spinning shaft from the engine to which the propeller is attached.
The cone pin, or shear pin, is used to attach the propeller to the drive shaft so that if you hit something hard with the propeller, you only break the shear pin, and not the expensive drive shaft, motor, or propeller.Or, more specifically, that you only break the shear pin and propeller, not the drive shaft or motor.
Weight savings.
A hollow shaft has a empty space inside, while a solid shaft is completely filled. Hollow shafts are lighter and can be more flexible, while solid shafts are stronger and stiffer. Hollow shafts are often used when weight is a concern, while solid shafts are used when strength is more important.

Main reason is to allow for the dynamics of the drivetrain. Secondary reason is to allow the shaft to collapse in a crash.
important reason behind inclining the shaft is to avoid/reduce various vibrations that may come up from the propeller and shaft rotation. various rulebooks have the minimum clearances for hull/propeller, so when the hull and propeller are designed and the minimum clearances are not satisfied shaft are inclined. other reasons include better positioning of engine bearers, better flow angle to the propeller blades
