Force Applied to Overcome Load
The force applied to overcome a load is defined as effort.
- Effort: The input force applied to a simple machine or system.
- Load: The resistance force or weight that the machine is working against.
- Weight: The force of gravity acting on an object. It may constitute a load but is not the applied force.
- Mechanical Advantage: The ratio of the load force to the effort force, expressed as \( MA = \frac{Load}{Effort} \).
- Velocity Ratio: The ratio of the distance moved by the effort to the distance moved by the load, expressed as \( VR = \frac{Distance_{effort}}{Distance_{load}} \).
Therefore, the correct term for the force applied to overcome a load is effort.
