Ideas for making a simple machine. ?

Question

So I have to create a design combining 3 simple machines. I'm not the most imaginative person, some ideas would be great!

Also.. it can't be too large.

Thanks so much (:

Answer 1

Sounds like a homework project:  Usually the term refers to the six classical simple machines which were defined by Renaissance scientists:

Lever

Wheel and axle

Pulley

Inclined plane

Wedge

s***w

An example would be to pull a small CART up a RAMP with PULLEYS... you can demonstrate the lower amount of force required to move a load over an obstacle with those three "MACHINES" than without.

GOOD LUCK
