What does lever mean in science?
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 can be increased on a lever?
the length of the fulcrum can be increased in proportion to the length behind the pivot point or leverage point. this will increase the power delivered by the lever. Also the force applied to the end of the fulcrum will also delivers more power from the lever. it is said amongst physic students and thier teachers that if you have a long enough lever and can place against the proper stationary pivot point (heal) you can move anything.
What is the pivot point of a lever?
The point it pivots round. That is when you use the lever which point on the lever does not move.
Why must you choose a stationary object as a reference point?
By the equivalence principles of relativity you do NOThave to choose a stationary point as a reference, Any point in space may be chosen as no point is truly "stationary" and a point that is stationary in one reference frame will be moving in another.
A rod that pivots about a point?
Lever, the fixed point is the fulcrum.
What is the name of the stationary point on a lever?
Cylind

What is the stationary point that used for speed measurement?
There is really no such thing as an absolute stationary point. By convention one can be picked as any point in the observer's frame of reference (i.e. any point stationary relative to the observer).
A rod that pivots about a point?
Lever, the fixed point is the fulcrum.
What is a term for the point of which a lever pivots?
The point where a lever pivots is called a fulcrum.
What is the fixed point on a lever that does not move?
The fulcrum is the fixed part of a lever. (the pivot point)
What is the name for the pivot point in a lever?
The pivot point of a lever system is called the fulcrum.
What is the pivot point of the lever system?
The pivot point of a lever system is called the fulcrum.
What part of a lever is the point where the lever rests?
fulcrum
