Examples of first-class levers include a seesaw, scissors, and a crowbar. In these levers, the fulcrum is located between the effort (force) and the load (resistance).
Your arm is a really good example
Lab tong, forearm, wrist
Some uncommon examples of third-class levers include tweezers, ice tongs, and some fishing rods. Third-class levers have the effort between the fulcrum and the load, increasing the speed and distance traveled by the load.
Some examples of first-class levers include a seesaw, scissors, and pliers. These levers have the fulcrum placed between the effort force and the load, allowing for a balanced distribution of force.
Some examples of second-class levers include a wheelbarrow, a nutcracker, and a bottle opener. In these lever systems, the resistance is situated between the effort and the fulcrum, allowing for increased force to be exerted to overcome the resistance.
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 .
Examples of third class levers in the body include the biceps during forearm flexion, the hamstrings during knee flexion, and the calf muscles during ankle plantar flexion. In these levers, the effort is applied between the fulcrum and the resistance, allowing for greater range of motion but requiring more force to move the load.
Some examples of linked second-class levers include a wheelbarrow and a bottle opener. In these systems, the resistance is between the fulcrum and the effort force, which allows for a mechanical advantage to be gained.
