The price difference of metal framing versus wood framing in Washington state and Texas will vary depending on the exact material that is being used. Typically though metal framing is cheaper then wood framing however the labor costs are higher.
Sleeve bearing
A couple primary reasons. 1 the current reversing itself helps to break up oxides on the surface of the metal. 2 Alternating current produces more heat in the arc which is useful in welding aluminum because heat dissipation is rapid in this metal.
It depends on the resistance to the current flow
Earth leakage current or ground leakage current is current going where it is not supposed to be going (whether it is on a laptop or not). Power line current should only flow between hot and neutral. The earth or ground line is only there for safety purposes to keep the metal chassis at 0V at all times.

Yes
Sleeve bearing
Depending upon your plans, it can be 5% to 20% of the cost. Are you building on a slab or conventional floor? Is your framing all wood or some metal? Is your wall coverings sheet rock or wood paneling? Your basic lumber framing package should be 10% excluding for labor.

bearing
There is no simple formula to calculate the metal bearing clearance. Manufacturers must specify the clearance for each individual bearing.
in friction type the bearing metal is direct contact with shaft metal, but in the antifiction the rolling element is contact with the bearing races only.
Hematite is a metal-bearing ore, but it's not a metal itself.
When a mechanical bearing becomes overheated for whatever reason, the lubricating material will become less viscous, and the danger of metal-to-metal contact increases. This will lead to the failure of the bearing.
