QUESTION 104 People who use objects whose operating principle is the same as that of levers apply a force, called the effort force, at a given point on the bar, to overcome or balance a second force, called the load force, at another point on the bar. Because of the different distances between the points of application of the effort and load forces, their effects are also different. The figure shows some examples of these objects. [Figure] In which of the objects is the effort force greater than the load force? (A) Tweezers. (B) Pliers. (C) Nutcracker. (D) Wheelbarrow. (E) Bottle opener.
