100

activity involving mental or physical effort done in order to achieve a purpose or result.


  • work
100

an apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task.


  • machine
100

the amount of energy supplied to the machine

  • work input
100

the state or quality of being efficient.


  • efficiency
100
a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.


  • wheel and axle
200


  1. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.




  • joule
200

the force you apply to the machine,

  • input force
200

the energy given by the machine to do useful work.

  • work output
200

a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.



  • lever
200

simple machine consisting of a sloping surface, used for raising heavy bodies

  • inclined plane
300

the ability to do something or act in a particular way, especially as a faculty or quality.


  • power
300

 the force that you would need to lift the object without the inclined plane


  • output force
300

a measure of the ratio of output force to input force in a system

  • mechanical advantage
300

a thing that plays a central or essential role in an activity, event, or situation.


  • fulcrum
300

a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.


  • wedge
400


  1. the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.




  • watt
400

the distance over which the input force is applie

  • input distance
400

the mechanical advantage determined by physical measurement of the input and output forces

  • actual mechanical advantage
400

The side of a lever on which force is applied


  • input arm
400

a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.


  • screw
500
a unit of power equal to 550 foot-pounds per second (745.7 watts).
  • horsepower
500

exerting a force over another distance

  • output distance
500

the mechanical advantage of a perfect machine with no loss of useful work caused by friction between moving parts.

  • ideal mechanical advantage
500

 the por- tion of the lever directly connected to the load.

  • output arm
500


a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.
