The function of a machine shaft is to transmit _____________.

Explanation:
A shaft’s job is to carry rotational motion and the torque that drives other parts of a machine. In other words, it transmits mechanical power from a driving element (like a motor or engine) to a driven element (such as gears or pulleys). It’s the rotating link that converts the source’s energy into work at the load. Electrical power, heat, and fluids aren’t carried by a shaft—electric power goes through conductors, heat moves via conduction/convection/radiation, and fluids flow through pipes or channels.
