The load is the resistance of the wood. With the human forearm, the fulcrum is the elbow, the biceps muscle supplies the effort, and the load is the wood's resistance. In addition to third-class levers, there are first- and second-class levers. One example of a first-class lever is a seesaw. An example of a second-class lever is a wheelbarrow.

Students will apply the concept of levers to the human body and design levers within a musculoskeletal context that meet the definitions of 1st, 2nd, and 3rd class levers. They will first learn the concept of levers, the parts of a lever, and what the different types of levers are used for. Next, they will be shown how the musculoskeletal system is a system of levers and one example of each type of lever. The students will be assessed on their ability to identify types of levers, parts of a lever, mechanical uses of each type of lever, and capacity to build all three types of levers.

A class three lever is where the load is one side of the force and the fulcrum is on the other side of the force. An example is a pair of tweezers. Another example is the seco … ndary lever in a pair of fingernail clips, i.e. the part that closes on the fingernail.

Confidence votes 97. The three kinds of levers are the: A) First-class lever - Like a seesaw, the fulcrum is in the middle. The input force is on one side and the output force comes out on the other side of the fulcrum. B) Second-class lever - This one is like a wheelbarrow.

Concepts: 1  A lever is a rigid body that rotates around a pivot point and exerts force on an object preventing its tendency to rotate. 2  1st class lever: effort and load are on opposite sides of the fulcrum; a small effort can be used to advantage over larger weight when using a larger lever arm.

Terms associated with levers: 1  Fulcrum: the pivot point of a lever. 2  Effort: the force applied to a lever. 3  Resistive force, load or resistance: force that resists the motion of the lever. 4  Moment arm: the perpendicular distance from the line of action of the force of the fulcrum. 5  Mechanical advantage: ratio of output force : input force.

Best Answer: A tree pruner is actually a double lever. Since the fulcrum (pivot point) is situated between the points where the outforce and the inforce are applied, it is indeed a 1st class lever. Locating the pivot and checking its relative position is the best way to recognize the lever type.
