Lever, simple machine machine, arrangement of moving and stationary mechanical parts used to perform some useful work or to provide transportation. From a historical perspective, many of the first machines were the result of human efforts to improve war-making capabilities; the term consisting of a bar supported at some stationary point along its length and used to overcome resistance at a second point by application of force at a third point. The stationary point of a lever is known as its fulcrum. The term lever is also applied to a projecting piece that is moved to operate or adjust inner machinery, such as a lever moved to the right or left to switch electric current on or off or to adjust the size of the opening of a shutter in a camera.

What does lever pivot and force mean in science?
In science, a lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the pivot or fulcrum. A force applied to one end of the lever can be used to move a load located at the other end, with the position of the pivot determining the mechanical advantage of the lever.
What the solid bar that rests on a fulcrum?
The lever? There are probably other names for it, but i was always taught the fulcrum, lever, and load. Load closer to fulcrum, easier to lift load. (longer lever= mechanical advantage) This would fall under simple machines in science class.
Describe the distance from the applied force to the fulcrum?
The distance from the applied force to the fulcrum is known as the effort arm. It plays a significant role in determining the mechanical advantage of a lever system. The longer the effort arm, the easier it is to overcome the resistance at the load end of the lever.
What type of lever is a gun?
well if you mean as in lever action there is winchesters with lever action ive seen a 10 gauge Winchester with lever action its a fine piece of wor i wish i could have shot it
What does raise with a lever mean?
Raising with a lever refers to using a lever, a simple machine, to apply a force in order to lift or move an object. By pushing or pulling on one end of the lever, the object on the other end can be raised or moved with less effort than if the force was applied directly.
What does fulcrum mean in science?
It is when a lever turns in moving a body.
What does lever pivot and force mean in science?
In science, a lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the pivot or fulcrum. A force applied to one end of the lever can be used to move a load located at the other end, with the position of the pivot determining the mechanical advantage of the lever.
What kind of lever is a shovel in science?
A shovel is most often operated as a Class-III lever, typically in snow.
What does lever mean in French?
The French word lever means to raise in English.The English word lever means levier in French.
What does class 1 lever mean?
A Class-1 lever is a lever with the force and the load (resistance) on opposite sides of the fulcrum (pivot).
Sentence for load in science term?
The lever, when pushed on, lifted the load. Hope this helps!

What do warning lites mean on gearshift lever Dodge Grand Caravan 1995?

How does physical science relate to a bicycle?
Well, part of physical science is simple machines and compound machines. The simple machines are the gear, screw, wedge, lever, pulley, and wheel and axle, and inclined plane. A bicycle is a compound machine. It is made up of the wheel and axle, gear, pulley, and lever. so it corresponds with that part of PHYSICAL SCIENCE. Hope this answer helped!!!
