In the human forearm, the elbow acts as the fulcrum, the applied force is the bicep muscle and the hand acts as the load.

The image below is an example of a Class Two Lever, sometimes called a Second Class Lever. An example of a first class lever is a seesaw or balance beam, an example of a second class lever is a wheelbarrow and an example of a third class lever is the human forearm. More force is required in a third class lever to move an object. A first-class lever is a lever where the fulcrum is in between the effort and resistance (the load). 2nd class levers are interesting, as the fulcrum is at one end, the applied force at the other, and the load that is to be moved is between them. 3. resistance is between axis and force; classic examples: wheelbarrow, nutcracker; complex example: rowing paddle in water acts as slipping axis (A) boat resistance is resistive force (R) rower is motive force (F) relatively few examples in body plantar flexion of foot to raise body up on toes And then a second-class lever is a stick where the fulcrum is at one end of the stick and you push on the other end. Examples of first class levers include see-saws, crowbars, pliers and scissors. Second class levers always provide a mechanical advantage. A great example of a Class 1 lever is a teeter-totter. Levers make it easier to lift heavy materials, remove tight objects and cut items. Second class levers always have the out put force between the fulcrum and the in put force, this ensures that it has a mechanical advantage. Some common second-class levers are doors, staplers, wheelbarrows, and can openers. Here’s my published coverage of that.

Each of the scissors, the pincer, the pliers and the nail clipper are composed of two first-class levers. A second-class lever is one in which the load, or the item being lifted, is found between the effort and the fulcrum, or pivot point. For example if you used a second class lever (like a wheelbarrow) to move 200 lbs of dirt by lifting with only 50 lbs of effort, the mechanical advantage would be four.

An example of second class lever is nutcracker where the nut (load here) is in the middle. Second class. Here the load lies between the fulcrum and the effort. Levers are one of the simplest machines. A second-class lever has a fulcrum at one end and a load in the middle. Example - Second-Class (Order) Lever. High School Physics. The lever which has a Load in between the Fulcrum(pivot) and Effort is called second class lever. The amount of force used internally by this simple machine is called as mechanical advantage of lever. 3. Third class lever – the effort is in the middle between the fulcrum and the load. The lever which has a Load in between the Fulcrum(pivot) and Effort is called second class lever. Examples of third class levers include a broom, a hoe, a fishing rod and a baseball bat.

In third class levers, the effort is between the load and the fulcrum. For a third-class lever, E is the middle component.

A wheelbarrow demonstrates this type of lever system. Give examples of second class lever. Wheel barrows, staplers and bottle openers are all good examples of second class levers. This second class lever is used when taking off for a jump or pushing against the blocks in a sprint start.

Why the body uses levers. Wheel barrows, staplers and bottle openers are all good examples of second class levers.
