How Steam Engines Work

Steam Engine

There are four parts needed to make a steam engine work and here they are.

1. A fire where the coal burns.

2. A boiler full of water that the fire heats up to make steam.

3. A cylinder and piston, a bit like a bicycle  pump but much bigger.  Steam from the boiler is piped into the cylinder causing the piston to move first one way then the  other.  This in & out movement (which is known as reciprocating) is used to drive……….

4. A machine attached to the piston.  That could be anything from a water pump to a factory machine, or even a giant steam locomotive  running up and down a rail track………..or Titanic!

Titanic Beneath

Today i am going to be writing about the titanic beneath and this photo was the last time titanic was seen and it was said that the Titanic  would never sink but it did. An Iceberg sunk the ship everyone said that the titanic would  never sink but sadly in did and 1500 people went into the sea. Luckly 6 were saved from the water but forthe other 1496 we feel sorry for the lost. One hundred and two years ago sank in 1912.
