A manometer instrument is used to check the alignment of two shafts.
The tunnel was built under two contracts. One contractor used conventional drill and blast to excavate the entire 40 ft. high by 20 ft. wide tunnel profile, working from the west portal. The east portal contractor excavated a +or- 20 ft. diameter top heading with a tunnel boring machine and then used drill and blast to remove the remaining "bench". The tunnel was lined with concrete after excavation was complete. A third contractor built the ventilation shaft. The tunnel uses a unique ventilation system that consists of the shaft, a tail tunnel connecting the shaft to the main tunnel and doors at either end of the tunnel and near the vent shaft tail tunnel. The doors open and close so as to push exhaust out the vent shaft or pull fresh air from the vent shaft into the tunnel, depending on the position of the train in the tunnel. The tunnel was built to reduce the grade for westbound coal trains. This reduced the need for up to nine additional locomotives to push the coal trains up the steeper grade of the Connaught Tunnel.

To find the diameter of a shaft through a bearing number, refer to the manufacturer's bearing catalog or specification sheet. Look for the bearing's bore size, which represents the inner diameter of the bearing. The shaft diameter should match the bore size to ensure proper fit and functionality.
the inner diameter is the shaft diameter the out diameter you have to calculated
6 is the diameter of the shaft and 32 is the number of threads it has per inch.
A phillips screwdriver is generally made of a steel shaft with a plastic handle
How do you find dia meter of shaft when bearing no is given?
inversly proportioal to cube of diameter

The medullary index measures the diameter of the medulla relative to the diameter of the hair shaft. MI= Medulla Diameter -------------------------- x 100 Hair Diameter
I am afraid not Depending on the size of the shaft on the thing you are putting on it is possible to get a bushing made to increase the size of the shaft. Go to your local machine shop and ask if they can make one.)
The condition in which a feature contains the maximum amount of material within stated limits. This condition is called as Maximum material condition (MMC) e.g.: Minimum hole diameter, maximum shaft diameter.
Depends on what you mean by "better". For the same dimensions, a solid shaft will be a bit stronger, but also a lot heavier. If you were to make a hollow shaft of the same weight, but a bigger diameter, it'd be a lot stronger than the solid shaft.
Labrynth seal clearances depend up the diameter of the rotating shaft, bearing clearance & temperature of the lubricating medium. As ageneral thumb rule the clearance must be 0.03 mm per 1" dia of shaft.
