activity involving mental or physical effort done in order to achieve a purpose or result.
an apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task.
the amount of energy supplied to the machine
the state or quality of being efficient.
the force you apply to the machine,
the energy given by the machine to do useful work.
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.
simple machine consisting of a sloping surface, used for raising heavy bodies
the ability to do something or act in a particular way, especially as a faculty or quality.
the force that you would need to lift the object without the inclined plane
a measure of the ratio of output force to input force in a system
a thing that plays a central or essential role in an activity, event, or situation.
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.
the distance over which the input force is applie
the mechanical advantage determined by physical measurement of the input and output forces
The side of a lever on which force is applied
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.
exerting a force over another distance
the mechanical advantage of a perfect machine with no loss of useful work caused by friction between moving parts.
the por- tion of the lever directly connected to the load.
