What two components make up mechanical power?

Mechanical power is fundamentally defined as the rate at which work is performed or energy is transferred. In the context of rotational systems, power can be expressed as the product of torque and rotational speed. Torque represents the rotational equivalent of linear force, while rotational speed denotes how quickly an object rotates around an axis. Therefore, the correct formulation for mechanical power in rotational systems is torque multiplied by rotational speed, making this answer accurate.

The other options, while related to the broader concepts of physics and mechanics, do not specifically represent the components typically associated with mechanical power in a rotational context. Force multiplied by speed relates more to linear motion, while energy multiplied by time does not capture the essence of power in mechanical contexts. Weight multiplied by distance represents work done against gravity rather than mechanical power itself.
