Engineering from the north east
Turbinia was built in 1894 by Charles Parsons and changed the face of maritime history.
Turbinia was built in 1894 by Charles Parsons and changed the face of maritime history.
• It was the first ship to be powered by a steam turbine and, in 1897, was the fastest ship in the world.
• Turbinia was built in 1894 by Charles Parsons and changed the face of maritime history.

Designing a ship
We need to follow a certain number of rules….
Two of the most important rules are:
1. The boat must float on top of
the water and remain
upright.
2. The boat must be able to
move.
Weight
Up thrust
1. The boat must float on top of the water and remain upright.
What physical factors do we need to consider to
achieve this?
Buoyancy (keeping a float) • When forces are balanced: Ships
float.
• Lower density - greater buoyancy
due to higher displacement of
surrounding water – Archimedes
Stability (Staying upright ) • Greater buoyancy = less stable
• Requires a low centre of gravity
Thrust Force > Drag Force
2. The boat must be able to move.
What physical factors do we need to consider to here?
Thrust
• When forces are balanced: ships
are stationary
Thrust Force = Drag Force
What needs to happen so that a ship can move
through the water and transport cargo from A to B!
Therefore;
Ship’s engines must provide enough power (thrust) to
overcome drag (water resistance, which is a form of
friction)
Which of these shapes is more streamlined
Vs. Curved Straight
edged
Vs. Smooth Rough
Designing our ship
Comparing
surface texture
2. Eliminating drag and resistance
Which of these shapes will create less drag on the ship?
…we need to test how efficient it is.
Once we have designed and made our own
ship….
Testing efficiency
High efficiency = $$$$$$$$
How does a streamlined boat save the shipping company money?
Less drag = Less fuel
Less fuel = Less pollution
Environmentally friendly:
Why do we worry about efficiency?
