Here are 9 great mechanical principles and inventions, which show the greatness of the human mind.
1: Opposing Pistons
2: Oval Regulation
3: Sewing Machines
4: Malta Cross movement -
second hand movement used to control the clock
5: Auto Change file mechanism
6: Auto Constant Velocity Universal Joint
7: Gun Ammunition loading system
8: Rotary Engine - an internal combustion engine,
the heat rather than the piston movement into rotary movement
9: Boxter Engine - it's cylinders lined up side by side
