Mechanical Systems and Simple Machines

Inclined Plane

  • An inclined plane is also known as a ramp.
  • It facilitates moving an object to a higher level.
  • The distance traversed along the inclined plane exceeds the height to which the object is raised.
  • A longer inclined plane reduces the force required to lift an object.
  • Function: Decreases the force needed to lift an object.

Screw

  • A screw is essentially an inclined plane wrapped around a pole.
  • Uses: Lifting objects or fastening them together.
  • Examples:
    • Swivel chairs
    • Jar lids
    • Screws

Wedge

  • A wedge is a V-shaped object used to split objects apart.
  • It functions in one direction only.
  • When splitting an object, the wedge moves a long distance into the object, creating a small gap.
  • Requires minimal work or force.

Levers

  • A lever is a simple mechanical system aiding in lifting, pushing, or pulling objects more easily.
  • Facilitates moving a large load with a small effort.
  • Effort is applied to the lever arm, which moves around the fulcrum.

Mechanical Advantage

  • Mechanisms utilize forces to make work easier.
  • Mechanical advantage (MA) is how much easier a mechanisms makes work.
