Understand the role levers play in our everyday lives. Learn what is a lever is, identify the classes of levers, and see examples.
We identify the resistance with the symbol FbFb. The segment between the fulcrum to the point of application of the resistance is denoted as bb. The effort is the force you apply when operating the lever. The distance from the point of application to the fulcrum is aa, while its value is...
A lever consists of four parts: the load, the fulcrum, the effort and the lever itself. The load is the point that exerts force on the object being manipulated by the lever, such as the bin of a wheelbarrow. The fulcrum is the point at which the lever pivots, such as the center of...
