What term refers to the power in an electric file machine or its ability to keep turning when applying pressure during filing?

1. Torque

2. Speed

3. Power output

4. Rotation

The correct answer is: Torque

The term that refers to the power in an electric file machine, specifically its ability to maintain rotation when pressure is applied during filing, is torque. Torque is a measure of rotational force and is crucial for tools such as electric nail files because it indicates how effectively the machine can continue operating under resistance. In nail technology, having sufficient torque is essential to enable consistent and smooth filing, preventing the motor from stalling when it encounters pressure. Understanding torque is vital for nail technicians as it impacts the speed and efficiency of the filing process. Higher torque allows for better performance when shaping or buffing nails, as it ensures the tool remains effective even with varying amounts of pressure applied. Other terms like speed and power output refer to different aspects of the tool's operation. Speed is concerned with how fast the bit rotates, while power output encompasses the total energy produced by the machine, but neither specifically addresses the ability to continue turning under load, which is what torque does.
