Question

name the type of lever which has a mechanical advantage always more than one. give an example. what change can be made in the lever to increase mechanical advantage

Answer me. Please

Answer 1

The elbow is the fulcrum, and the muscles of the forearm apply the force between the elbow and the hand. The class 3 lever always has a mechanical advantage of less than 1, because the load travels a greater distance than the force travels. Consequently, the work requires more effort than would ordinarily be needed.The advantage of levers, which relates effort and load (or input and output force), depends on how far away each are from the fulcrum. The mechanical advantage of a lever is increased when either the effort is moved further away from the fulcrum or the load is shifted closer to the fulcrum, or both.
