Which term describes using a great force against a weaker resistance?

• A. Balance displacement
• B. Pain compliance
• C. Leverage
• D. Mechanical compliance

Answer: (C)

Leverage describes using a lever to create a mechanical advantage, so you can affect a resistant target with greater effect than your raw effort might suggest. The idea is torque: force times distance from a pivot. By applying force farther from the pivot (or using a longer lever), you multiply the output force at the point of contact, making it easier to overcome a weaker resistance. In practice, your body and an arm or limb can act as the lever, with a fulcrum such as a joint or the floor, allowing you to control or move a resisting part with less direct effort.

Pain compliance relies on pain to gain control, which is not about multiplying force. Mechanical compliance means yielding or giving in to force, not enhancing your own applying force. Balance displacement isn’t a standard DT term for this concept. So the term that best fits "using a great force against a weaker resistance" is leverage.
