Propeller torque force consumes quite a bit of the shaft horse power. Other forces involved... Centrifugal force imposes considerable stress, torque reaction tends to bend the blades in the reverse direction of rotation, the thrust force tends to bend the outer sections of the blades forward and turning moments tend to twist the blades to a decreased pitch. The air inflow at the face of the propeller disc also affects propeller dynamics

Propeller shafts experience primarily torque and bending forces as they transmit power from the engine to the propeller. Torque is the rotational force applied to the shaft, while bending forces can result from irregularities in the shaft's alignment or from external factors such as waves or collisions. Proper maintenance and alignment are crucial to minimize wear and ensure smooth operation.

What makes a propeller spin?
A propeller is connected to a drive shaft which is connected to an engine that runs the same way as a car
How does a propeller shaft work?
A propeller shaft transmits power from the engine to the propeller for propulsion in boats or aircraft. It consists of a long, straight shaft with universal joints that allow it to transfer torque while adapting to changes in angle or alignment between the engine and the propeller. As the engine turns the shaft, the propeller spins and generates thrust to move the vehicle forward.
How can a boat move at constant velocity if it's propeller provides a steady force to it?
Terminal velocity, where the driving force = drag force from the water
How can a boat move at constant velocity if its propeller provides a steady force to it?
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.
What are the type internal forces induced in a truss due to the externally applied loading?
The internal forces induced in a truss due to externally applied loading are tension and compression. Tension forces act to elongate the members of a truss, pulling them apart, while compression forces act to shorten the members, pushing them together. These internal forces enable the truss to maintain its structural stability and support the applied loads.
What is propeller shaft?
The spinning shaft from the engine to which the propeller is attached.
Why propeller shaft of a vechile is made hollow?

What is the function of the propeller shaft?
The function of anything with the word "propeller" on any vehicle is the object that "propels" the vehicle, or makes it move. A propeller shaft on a car links between your differential and you transfer case or transmission. The engine essentially rotates the gears in your transmission which in turn rotates the prop shaft itself, or the gears in the transfer case, which also rotates the propeller shaft. The shaft then turns the gears in the differential. The gears in the differential then turn you axles, which in turn rotate your wheels, propelling the vehicle. As for an airplane, a propeller forces air in the direction of the rear of the plane thrusting (propelling) the plane forward. Same idea with a boat only it forces water back causing the boat to be propelled forward.

Why is propeller shaft inclined?
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

Are thrust loads at a right angle to a shaft?
On a ships propeller shaft, the thrust will be in line with the axis of the shaft.
Why cone pin is used in propeller?
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.
