Da Vinci Machines by Harrison

These are machines that Leonardo Da Vinci Thought Of!!!!!

Question 1!

What Machine uses the most Friction? Explain?

The ball bearing machine because if you spin the machine fast then friction will slow the balls down.

Question 2

What machine uses the least amount of friction? Explain?

The Robot Knight because instead of you drumming down the street while holding a drum, this machine will do it for you. Also I don`t think this thing uses friction at all.

Question 3

What machine uses lots of gravity?

The lifting bags because it is extremely heavy and if you drop the bags it will hit the ground with a loud bang.

Question 4

What machine reduces gravity?

The Airscrew because it is kind of a old version helicopter but without the prepeler.

Question 5

What is your favourite Da Vinci Machine?

The water wheel is my favourite machine because it can easily carry water from the river up to your bucket.
