to prevent live conduit in case of short circuit
Adding an extra length of shaft on the existing shaft to take extra pulleys will put an extra load on the bearings supporting the shaft. In the long term this would shorten the life of the bearings. The makers might be able to supply more information like the side-load specification for the bearings. If in doubt support the outer end of the shaft.
rigid metal intermediate metal rigid nonmetallic
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
Conduits shall be supported at intervals not exceeding 3000mm.
is it permitted to use flexible metal conduit over 6 ft in length as a grounding means
Intermediate Metal Conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded.
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
No, each conduit must contain a separate grounding conductor.
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
It will induce a slight (as in negligible and unnoticeable) current in the conduit.

depends on size....
Yes, as long as it is in a plastic conduit.

In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
