An arm is another example of a third class lever. The elbow area is the Fulcrum, the upper arm muscle acts as the force, and the load will be located in the hand, which could be used to lift, push, or grab. A broom is another example of a Class Three Lever. Notice the similar locations of the Fulcrum, Force, and Load. Simple Machines Examples.

Third-class levers have an input force, a fulcrum and an output force. The placement of the fulcrum, input and output forces of the lever determines its type. A lever is a simple machine where a rigid arm is attached around a fixed point. This fixed point is called a fulcrum. The force that is put on a lever is called an input force.

This second class lever is used when taking off for a jump or pushing against the blocks in a sprint start. 3. Third class lever – the effort is in the middle between the fulcrum and the load.

A class 3 lever does not have the mechanical advantage of class-one levers and class-two levers, so examples are less common.The effort and the load are both on the same side of the fulcrum, but the effort is closer to the fulcrum than the load, so more force is put in the effort than is applied to the load.

ExRx.net notes that most levers in the body are third-class levers, in which force is applied between the fulcrum and the resistance. A shovel is an example. A shovel is an example. Biceps curls employ a third-class lever, with the force being exerted by the bicep muscle between the fulcrum at the elbow joint and the weight in your hands.
