A Rube Goldberg Invention
2
Rube Goldberg

• This is Websters definition
• A contrivance or method to accomplish an
  apparently simple task in an extremely complex
  way
• So much for the K.I.S.S. method!
• (Keep It Simple Sweetie)

Who was Rube Goldberg?

• He lived at the turn of the last century.
• He loved poking fun at all of the modern
  conveniences that were being developed at the
  beginning of the 20th century.

A little more about Mr.Goldberg

• Reuben Lucius Goldberg studied at the University
  of California at Berkeley.
• After graduating in 1904, he started working as a
  sports cartoonist for the San Francisco
  Chronicle.
• In 1907 he moved to New York after selling his
  Sunday half-page strip 'Mike and Ike'. This comic
  didn't generated much response.
• He eventually landed a job at the New York
  Evening Mail.
• Apart from drawing comics, he also took a shot at
  vaudeville, becoming a stand-up comedian and
  fortune-teller in 1911!

• Rube Goldberg gets his think-tank working and
  evolves the simplified pencil-sharpener.
• Open window (A) and fly kite (B).  String (C)
  lifts small door (D) allowing moths (E) to escape
  and eat red flannel shirt (F).   As weight of
  shirt becomes less, shoe (G) steps on switch (H)
  which heats electric iron (I) and burns hole in
  pants (J).   Smoke (K) enters hole in tree (L),
  smoking out opossum (M) which jumps into basket
  (N), pulling rope (O) and lifting cage (P),
  allowing woodpecker (Q) to chew wood from pencil
  (R), exposing lead.  Emergency knife (S) is
  always handy in case opossum or the woodpecker
  gets sick and can't work.

Rube Goldberg has inspired many inventors.

• Its meant to be an elaborate way to get a very
  simple thing done

Simple Machines

• Rube Golberg used a variety of simple machines
  put together in a complex way to perform a simple
  task.

What is a Simple Machine?

• A simple machine has few or no moving parts.
• Simple machines make work easier

10
Simple Machines

• Levers
• Pulleys
• Inclined planes
• Wedge
• Screw
• Wheel and axle

11
Simple Machines

• Are used to hunt, gather plants, make clothes,
  build shelter, and protection
• They copy nature such as
• Beavers cutting logs
• Woodpeckers pecking on a tree trunk
• Moles clawing their way through the dirt

12
Levers

• Levers make it easier for people to lift heavy
  objects or open things.
• The object being moved or opened is called the
  load.
• The force that is exerted is the effort.
• Fulcrum is the fixed point that allows a pivot to
  occur.
• In every lever there is an ELF.

13
Levers-First Class

• In a first class lever the fulcrum is in the
  middle and the load and effort is on either side
• Think of a see-saw

14
Levers-Second Class

• In a second class lever the fulcrum is at the
  end, with the load in the middle
• Think of a wheelbarrow

15
Levers-Third Class

• In a third class lever the fulcrum is again at
  the end, but the effort is in the middle
• Think of a pair of tweezers

16
Inclined Planes

• An inclined plane is a flat surface that is
  higher on one end
• Inclined planes make the work of moving things
  easier
• Ramps are inclined planes
• You must travel a greater distance

17
Screws

• A screw is an inclined plane wrapped around a
  shaft or cylinder.
• The inclined plane allows the screw to move
  itself when rotated.

18
Wedges

• Two inclined planes joined back to back.
• Wedges are used to split things.

19
Wheels and Axles

• The wheel and axle are a simple machine
• The axle is a rod that goes through the wheel
  which allows the wheel to turn
• Gears are a form of wheels and axles

20
Pulleys

• Pulley are wheels and axles with a groove around
  the outside
• A pulley needs a rope, chain or belt around the
  groove to make it do work

21
Gears

• A wheel with teeth
• Used to transfer power
• One gear cannot work on its own
• Many gears are connected with chains

22
Compound Machines

• Simple Machines can be put together in different
  ways to make complex machinery.
