In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. In order to move or hold a load the created by the effort must be large enough to balance the caused by the load. This simulation includes the effects of friction, so you can see how in the joint () works to stop motion and contributes to maintaining by resisting a start of motion.

For the lever system formed by the biceps calculate the length the muscle has shortened compared to the distance the hand moves. Levers with the resistance (load) in-between the effort and the fulcrum. For example if you used a (like a wheelbarrow) to move 200 lbs of dirt by lifting with only 50 lbs of effort, the mechanical advantage would be four.

Muscles and Bones as Simple Machines in the Body Activity. Define fulcrum, resistance and effort (FRE). In such a lever, the load is located on the opposite side of the fulcrum as the applied force. This will be done as a group with one piece of paper and the first person verbalizing the activity and the lever while writing down their answer. A pulley system operates on the principle that a load can be lifted easier by pulling on a rope or cable that is wrapped between a supporting structure and a rigid fixture attached to the load itself.
Therefore, the act of plantarflexion can move much more weight than elbow flexion, even if your bicep is just as strong as your calf. That seems like a mechanical disadvantage, so how is that helpful? In this, the fulcrum is at one end and the force applied is on the other end. Extension Experiments.

Step: Present & Explain. Classroom Considerations. The lever is the most familiar of all the simple machines because of its plain construction and extensive use in numerous engineering devices. Science & Engineering Practices||Disciplinary Core Ideas||Crosscutting Concepts|. In this diagram below, the load and weight of the lower leg produce a clockwise torque about the knee. Then from the general definition, we see the mechanical advantage of the wheel-and-axle depends only on the radius of each, where it can be written as: This result informs engineers how the mechanical advantage of a wheel-and-axle may be altered to provide the most efficient results in an engineering system. The more force applied and the further the load is moved, the more work is done.
To understand how this is achieved, it is necessary to recall that work is done by applying force to a load and transporting it over some distance. In other words: If MA < 1, then work is harder, but faster. The greater the mass of the object, the greater the force needed to achieve the same change in motion. Your skull is the lever arm and the neck muscles at the back of the skull provide the force (effort) to lift your head up against the weight of the head (load).
