Final answer:
Explanation of mechanical advantage, velocity ratio, and efficiency in relation to formulas.
Explanation:
Mechanical Advantage: The ratio of output force to input force is known as mechanical advantage (MA). It can be calculated by dividing the load arm by the effort arm.
Velocity Ratio: The ratio of output distance to input distance is the velocity ratio. It determines how much the input distance is multiplied to produce the output distance.
Efficiency: The efficiency of a machine is the ratio of its output work to input work, indicating how well the machine converts input work to useful output work.
