The propeller shaft in a boat engine is fastened to the flywheel by bolts, and it passes through the boat's thrust block and is aligned with the shaft tunnel. It also passes through the stern tube to drive the propeller.
The stern tube shaft itself holds the "prop" shaft in place and shut off the open end when it pierces the aft hull. It is commonly manufactured as cast iron and welded into the frame of the stern of the ship.
The stern tube in marine engineering allows the propellor shaft to penetrate the hull of a ship and prevent the ingress of water. It also acts as a bearing and lubricates that part of the shaft.
at least in small scale, the propeller shaft is run through a tube almost the same size as the shaft but filled with a water proof grease and held in the tube by a cap at the end, (much like a hydraulic piston, it can travel through it but doesn't leak fluid) there are also water tight bearings that the shaft can be ran through. i cant imagine large scale would be much different
as in solid rod there has more free electrons which will cause more current than a hollow metal tube of same dia/length/material.
Normally using a calibrated bellows or bourdon tube. As pressure is sensed by the device it inflates the tube or bellow which in turn causes the needle to rotate. Pre-seventies pitot and static systems on aircraft use this very technology to relay information like true air speed to the pilots.
no need to change the copper tube if the capacity of the unit is same.
It is a tunnel-like opening at the vessel's stern, through which the propeller or tail shaft passes, in order to connect the propeller to the engine.

Oil lubricated and sea water lubricated stern tube
To make a paper tube airplane, you will need a paper tube, paper for wings, a propeller, and glue. Cut the paper tube to the desired length for the body of the airplane. Attach the paper wings to the tube, and add a propeller to the front. Decorate as desired.
The fadec sends a signal to the pcu which in turn ports oil through a beta tube into the cylinder to either the front or backside of the piston to move the blades. The piston is connected to a crosshead assembly inside the propeller hub which slides up and down with the piston to move the blades

No. Levin tube is not the same as the Blakemore tube.
it houses stern tube,give strength to aft portion,give profile to aft deep tank,support stringing member
