Which component of a steam turbine converts steam force into rotational motion?

• A. Blades
• B. Rotor
• C. Compressor
• D. Thrust bearing

Answer: (A)

In a steam turbine, the component that converts steam force into rotational motion is the blades. The blades are designed to interact with the steam flow, capturing the energy from the high-pressure steam as it passes over them. As steam hits the blades, it exerts a force that causes them to spin around the rotor, thus generating rotational motion. The design and angle of the blades are crucial because they must effectively harness the kinetic energy of the steam and convert it into mechanical energy. This process is fundamental to the operation of steam turbines, which are widely used for power generation in power plants. The steam is directed through a series of blades, and as it expands and cools, its energy is transformed into movement of the turbine's rotor. In contrast, the rotor itself plays a supportive role by providing a shaft around which the blades rotate, while a compressor would be involved in gas compression rather than steam turbine operation. Similarly, a thrust bearing supports axial loads in machinery but does not convert steam energy into motion.
