Is an elevator a second class machine?
Yes, an elevator can be considered a second-class machine. In a second-class lever, the load is positioned between the effort and the fulcrum, much like how an elevator uses a counterweight system to lift the car. The force applied (effort) moves the elevator car (load) vertically, with the pulleys acting as the fulcrum. This design allows for more efficient lifting of heavy loads with less effort.
Is a peg a lever?
A peg is not a lever in itself; it is a simple object that can be used in conjunction with levers. A lever is a rigid bar that pivots around a fixed point called a fulcrum, allowing for the amplification of force. While a peg can serve as a fulcrum or part of a lever system, it does not embody the mechanical principles of a lever on its own.
What is the relationship between the load and effort that gives a lever system an adavantage?
the relationship between them is that the load carries it self and the lever holds its self in place

What are the wee hours in Cannes?
The wee hours in Cannes are referred to as 'lever du soleil' or 'lever de soleil' which means dawn or sunrise.
What is a support called on a lever?
inclined plane
Where are the effortloadand fulcrum located in a first class lever?
In a First Class lever, the fulcrum is between the effort and the load.
What is the part of a lever on which the effort force is applied is called?
Fulcrum
In what order do the effort fulcrum and resistance appear on a second class lever?
On a second class lever, the effort is applied at one end of the lever, while the resistance is located in the middle of the lever, between the effort and the fulcrum.
What describes the distance from the applied force to the fulcrum?
The distance from the applied force to the fulcrum is called the effort arm or lever arm. It is the perpendicular distance between the line of action of the force and the fulcrum in a lever system. The length of the effort arm affects the mechanical advantage of the lever.
What are the fulcrum resistance and effort?
A fulcrum is the fixed point around which a lever pivots. The resistance is the force opposing the movement of the lever, while the effort is the force applied to move the lever. The position of the fulcrum relative to the resistance and effort forces determines the mechanical advantage of the lever system.
How do you measure the effort distance in a lever?
The effort distance in a lever is measured from the point where the effort force is applied to the fulcrum. It is the distance over which the effort force acts to move the lever. By measuring this distance, you can calculate the mechanical advantage of the lever.
What is a lever's effort arm?
It is the part of a lever, where external force is applied in order to do work.
What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
What class lever is a pen?
A pen is a class 3 lever - the effort is applied between the load and the fulcrum.
What. Are the parts of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
Where is the fulcrum located on a class 3 lever?
In a class 3 lever, the fulcrum is located at one end, the effort is applied at the other end, and the load is in between. This type of lever is characterized by having the effort in the middle, being closer to the fulcrum than the load.
