Two triple expansion steam engines and an exhaust turbine
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
Because different engines have different advantages. Steam engines can be run from anything that burns, but are big and heavy. 2-stroke (gasoline) engines has great power-to-weight ratio, but tend to use a lot of fuel and create a lot of emissions. 4-stroke Diesel engines tend to run rougher and don't rev as high as gasoline engines but are more fuel efficient and often have more torque.

The branch of science and technology concerned with the design, building, and use of engines, machines, and structures
The engines did not fail. Unfortunately they drove Titanic into the iceberg with resounding success.
Nobody reversed the engines anytime during the night Titanic was struck, but briefly, the engines were turned on.
The engines were powered by boilers
Non, because Titanic didn't use fuel. She used coal, instead of fuel.
Engine, as in the steam engines that powered the Titanic.
Titanic was steered (unsuccessfully) to avoid the berg but the engines were not reversed.
The RMS Titanic used 2 triple-expansion steam engines, each weighing 1,000 Tons (2 million pounds each). Source: Titanic-Titanic.com (see link below)
The three Olympic-Class vessels, including Titanic, were designed By Alexander Carlisle.
The Titanic had funnels to get rid of low pressure steam after it had been used to drive the engines.
No, it was a cruise liner, it had coal powered engines

I don't know what you mean. If you mean who could operate the engines then any senior officer while he was on watch. If you mean who was the officer who reversed the engines when Titanic hit the ice burg then it is 1st officer William Murdoch.
