The examples of levers of second class are :--
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
First class levers are like see-saws. The fulcrum (turning point) comes between the effort and the load. So if you push down on the effort the load goes up. With second class levers the load comes between the effort and the fulcrum. This is good for catapulting things. Third class levers have the effort between the load and the fulcrum. An example would be a fishing rod. The fish on the end is the load, your hand on the rod is the effort and the hand at the end is the fulcrum.

In a second-class lever, the load is positioned between the effort and the fulcrum. This arrangement allows the effort applied to move the load more easily, as the distance from the effort to the fulcrum is greater than the distance from the load to the fulcrum. Common examples of second-class levers include wheelbarrows and nutcrackers.
No, but wheelbarrows are.
Second class levers have the load between the fulcrum and the effort (load-fulcrum-effort), while third class levers have the effort between the load and the fulcrum (load-effort-fulcrum). Second class levers provide mechanical advantage and are more efficient for lifting heavy loads, while third class levers provide a speed advantage but require more effort.
The distinguishing characteristic of first-class levers is that the fulcrum lies between the effort force and the resistance force. Second-class levers have the resistance force between the fulcrum and the effort force. Third-class levers have the effort force between the fulcrum and the resistance force.
There are three basic types of levers: first-class, second-class, and third-class. These levers differ based on the placement of the fulcrum, effort, and load.
First-class levers increase or decrease the force applied, second-class levers increase the force applied, and third-class levers increase the distance moved.
Some disadvantages of second-class levers include the fact that they require a larger input force compared to first-class levers to achieve the same output force. Additionally, the load is situated closer to the fulcrum, which can limit the range of motion and force that can be applied. Second-class levers also have a fixed pivot point, which may restrict their versatility in certain applications.

There are three classes of levers: first-class, second-class, and third-class. These classes are based on the relative positions of the fulcrum, effort, and load.
Levers can be found in various systems such as tools, machines, and human body. There are three types of levers based on the relative positions of the fulcrum, resistance, and effort: first-class lever, second-class lever, and third-class lever. Examples include seesaws (first-class), wheelbarrows (second-class), and shovels (third-class).
Lever belongs to the category of simple machines. They are three types of levers 1. First class levers 2. Second class levers 3. Third class levers In the first class levers fulcrum is in between applied force and load. common examples are Crowbar , Pair of scissors , SeeSaw , Skull and neck in our body .
Some disadvantages of second-class levers include that they require a lot of force to move the load as the effort arm is shorter than the resistance arm. They also tend to have limited range of motion compared to first-class levers and are less common in nature and technology.
The three types of levers are first-class, second-class, and third-class levers. In a first-class lever, the fulcrum is positioned between the effort and the load, like a seesaw. A second-class lever has the load between the fulcrum and the effort, such as a wheelbarrow. In a third-class lever, the effort is applied between the fulcrum and the load, exemplified by a pair of tweezers.
