How can the answer be improved?Apr 25, 2017 While the many advantages of levers are well known, the system has several disadvantages as well. At its most basic, a lever is a straight, rigid object that pivots on a fulcrum to ease lifting by using a small force applied over a large distance. There are three types of levers. advantages of first class lever system

1) Measure the mass of a single penny and record this information. 2) Set up a first class lever using a pencil for the fulcrum and ruler. Place the pencil (fulcrum) 2 times closer to the load than the effort and tape it to the ruler. Then tape a cup to either end of the ruler.

The mechanical advantage of a second class lever is always greaterthan one. The mechanical advantage of a first class lever rangesfrom 1 to infinity. Apr 25, 2017  Practical Advantage. Firstclass levers have a considerable practical advantage over the other types of levers. They convert a downward moving force into a lifting force. This means that you can always augment your ability to lift a load across a teetertotter style lever advantages of first class lever system A firstclass lever, in which the fulcrum is between the load and the effort, can aid in work by changing the direction of the force and by increasing the efficiency or mechanical advantage of the force applied. The force exerted on a firstclass lever has greater mechanical advantage proportional to its distance from the fulcrum. Continue Reading.

(Think of a seesaw). In this case the force closest to the fulcrum is greater, but moves a shorter distance. So these can either provide speedup or mechanical advantage, depending on Oct 27, 2017  The first class lever is one of three classes of levers and is one possible arrangement of muscles, bones, and joints found in the human body. While less common in the body than second and third class levers, the first class lever system is found in the neck at the atlantooccipital joint and in May 30, 2007  In a 3rd class lever system, you apply a large force, but over a small distance. This is useful in something like a broom, where your arm moves in small backandforth motions, but the broom bristles sweep in a wide backandforth motion down at the level of Start studying Lever System.
