A lever consists of: a rigid structure (bone) a force acting upon it (muscle) to produce a turning movement (angular motion) a fulcrum which is a fixed point (joint) a load or resistance that is placed on the rigid structure (weight of body part being moved and anything that it is carrying)
People also ask, what is a lever system?
A lever system is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by lever systems that are formed by our muscles and joints working together.

Height of release is the height from the ground that the object is launched. All badminton shots require correct height of release to be effective.

Examples of levers in everyday life include teeter-totters, wheelbarrows, scissors, pliers, bottle openers, mops, brooms, shovels, nutcrackers and sports equipment like baseball bats, golf clubs and hockey sticks. Even your arm can act as a lever.
Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance. In summary, in a first class lever the effort (force) moves over a large distance to move the load a smaller distance, and the fulcrum is between the effort (force) and the load.
Some examples of the wheel and axle include a door knob, a screwdriver, an egg beater, a water wheel, the steering wheel of an automobile, and the crank used to raise a bucket of water from a well. When the wheel in a wheel and axle machine is turned, so is the axle, and vice versa.
There are three types or classes of levers, where load and effort are located in relation to the fulcrum. The first-class levers are an integer between effort and load. The second-class levers are loaded between effort and fulcrum. And the third-class levers are between load and fulcrum.
Second Class Levers
If the load is closer to the effort than the fulcrum, then more effort will be required to move the load. A wheelbarrow, a bottle opener, and an oar are examples of second class levers.
