Joint Anatomy and Basic Biomechanics

With a first-class lever, the longer the lever arm is, the less force is required to overcome the resistance. The force arm may be longer, shorter, or equal to the resis-tance arm, but the axis will always be between these two points. An example of a first-class lever

Impulse of Force

Impulse of Force The product of average force and the time it is exerted is called the impulse of force. From Newton''s second law the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant:

Balancing act: the physics of levers |

When you use a lever, you apply a turning force (the moment) around the pivot to move the load. Moments reduce the effort needed to move the load by increasing the distance over which it is acting. This explains why less force is needed to open a door by pushing at the side furthest from the hinge than at the side closest to the hinge.

The musculoskeletal structure of the foot and ankle has the potential to influence human sprinting performance in complex ways. A large Achilles'' tendon moment arm improves the mechanical advantage of the triceps surae but also produces larger shortening velocity during rapid plantarflexion, which detracts from the force-generating capacity of the plantarflexors. The lever arm of the ground ...

What levers does your body use? — Science Learning Hub

There are four parts to a lever – lever arm, pivot, effort and load. In our bodies: bones act as lever arms joints act as pivots muscles provide the effort forces to move loads load forces are often the weights of the body parts that are moved or forces needed to lift, push

Torque

A force applied perpendicularly to a lever multiplied by its distance from the lever''s fulcrum (the length of the lever arm) is its torque.A force of three newtons applied two meters from the fulcrum, for example, exerts the same torque as a force of one newton applied six metres from the fulcrum. ...
