Mell What is in the middle of a second class lever?
In a second class lever system, the load is the middle component and lies between the fulcrum and the effort.
Where is the input force on a lever?
All levers include a stiff structure (the lever) that rotates around a fixed point called the fulcrum. The side of the lever where the input force is applied is called the input arm.
Which type of lever has the force in the middle?
First class levers have the fulcrum in the middle, between the load and resistance. Second class levers have resistance in the middle. Third class levers have the effort in the middle.
What is the position of load in 2nd type of lever?
In a second class lever, the load is located between the effort and the fulcrum. If the load is closer to the fulcrum than the effort, then less effort will be required to move the load. If the load is closer to the effort than the fulcrum, then more effort will be required to move the load.
Where is the fulcrum in a second class lever?
In a first class lever, the fulcrum is located between the input force and output force. In a second class lever, the output force is between the fulcrum and the input force. Beside this, what is an example of a 2nd class lever? In a Class Two Lever, the Load is between the Force and the Fulcrum.
How to calculate the load position of a second class lever?
In the 2nd class lever, the fulcrum and effort are at the opposite ends of the lever. Example: Calculate the load position of a second-class lever if its total length is 40 cm, the effort force is 10 N and the load force is 20 N. Input. Total length of the lever. L=AE.
How is the mechanical advantage of a lever defined?
The mechanical advantage of the lever is defined as the ratio of the output force (load) FL to the input force (effort) FE: The load force can be defined from this equation: There are three types of levers depending on the relative positions of the fulcrum, the effort and the load (or resistance).
Which is an example of a Class 3 lever?
Class 3 Levers: The fulcrum and the load are located on the opposite sides of the lever. The effort is applied between the load and the fulcrum. The examples are a broom, a human arm, and a fishing rod. In the third-class levers, the mechanical advantage is always less than one and the effort arm is always smaller than the load arm.
