What is the definition of a wedge?
A cylinder with a spiral ridge or thread running round the outside.
A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
Something that taper to a thin edge and is used for separating or blocking things.
The point around which a lever turns or is supported.
What is the definition of a screw?
A cylinder with a spiral ridge or thread running round the outside.
A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
Something that taper to a thin edge and is used for separating or blocking things.
The point around which a lever turns or is supported.
What is the definition of a fulcrum?
A cylinder with a spiral ridge or thread running round the outside.
A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
Something that taper to a thin edge and is used for separating or blocking things.
The point around which a lever turns or is supported.
What is the definition of a wheel and axle?
A cylinder with a spiral ridge or thread running round the outside.
A mechanical device consisting of a levr that rotates 360 degrees on a fulcrum.
Something that taper to a thin edge and is used for separating or blocking things.
The point around which a lever turns or is supported.

What is the definition of an inclined plane?
A flat surface set at an angle used to help raise or lower objects.
The point around which a lever turns or is supported.
A rigid bar resting on a pivot point or fulcrum, used to move a load with one end when pressure is applied to the other.
A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
What is the definition of an pulley?
A flat surface set at an angle used to help raise or lower objects.
The point around which a lever turns or is supported.
A rigid bar resting on a pivot point or fulcrum, used to move a load with one end when pressure is applied to the other.
A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
What is the definition of an lever?
