The lift capability of the rotor system is limited by which factor?

Explanation:
Lift is controlled by blade pitch through the collective, so the highest thrust you can achieve is set by how far you can physically move the collective. The actual collective stop is the fixed mechanical limit of that travel; once you reach it, you can’t increase blade pitch any further, and thus can’t generate more lift—even if engine power, rotor speed, or torque could otherwise allow it. So the limiting factor for rotor lift capability is the actual collective stop.
