As current passes through steel, it heats up from resistive heating. As it heats up, it expands. A typical coefficient of thermal expansion for steel is 13x10-6 m/m K but the exact coefficient of thermal expansion of steel depends on the type of steel. For example:
Coefficient of Linear Thermal Expansion for:
(10-6 m/m K)(10-6 in/in oF)Steel13.07.3Steel Stainless Austenitic (304)17.39.6Steel Stainless Austenitic (310)14.48.0Steel Stainless Austenitic (316)16.08.9Steel Stainless Ferritic (410)9.95.5
The steel would EXPAND
Linear Temperature Expansion Coefficient (10-6 in/in oF) Brass = 10.4 Steel = 7.3 Therefore brass will expand or contract more steel.
NO.
Agriculture, steel, jucie, clean water supplying industries.
To allow the steel to expand without cracking on a hot day.
At the utility company supplying power and water to your home.
The only reasons to expand trade is for money (profit) and power.

The effectiveness of wind power depends on where the wind power is coming from. Certain locations with a lot of wind are deemed effective at supplying wind power.
Edison was the first to build and run a power station, on a small scale but supplying a number of consumers
for expanding negative powers of a number you take 1 divided by the number to the positive power and expand. For example 2 to the -1 power is 1 divided by 2 to the + 1 power = 1/2 2 to the -3 power is 1 divided by 2 tot he + 3 power = 1/8 this is called inverse
