What characteristic is true of a second class lever?

In a second-class lever, the defining characteristic is that the resistance force is located between the fulcrum and the applied movement force. This arrangement allows for a mechanical advantage where the force applied can be less than the load being moved, making it easier to lift or move heavier objects.

For example, when using a wheelbarrow (a common example of a second-class lever), the wheel acts as the fulcrum, the load is placed in the bucket of the wheelbarrow, and the person lifting the handles applies the movement force. This positioning allows the user to lift a heavy load with less effort compared to the weight of the load being lifted.

The other options describe characteristics that do not fit the definition of a second-class lever. In a first-class lever, the fulcrum is located between the load and the effort, while in a third-class lever, the effort is applied between the fulcrum and the load. Therefore, option C accurately detects the structural setup of a second-class lever, highlighting its efficiency in force application when moving resistance.
