Which of the following allows equipment to start up virtually load free?

• A. Fluid coupler
• B. Stator
• C. Turbine
• D. Torque converter

Answer: (A)

A fluid coupler lets the engine start and accelerate without a strong direct load on it. It transmits power through oil between the engine-driven impeller and the output side while allowing slip between them. That slip means the drivetrain isn’t locked to the engine at startup, smoothing acceleration and absorbing shocks, which feels like a near load-free start for the engine. The other parts listed are components of a torque converter, which does provide smooth torque but involves circulating fluid and, especially at low speeds, more interaction than a simple fluid coupler. So the fluid coupler best provides a nearly load-free initial start.
