Question

    If the vector sum of torques acting on a system is zero,

    then the object is in ________.
    A Static equilibrium Correct Answer Incorrect Answer
    B Translatory equilibrium Correct Answer Incorrect Answer
    C Linear equilibrium Correct Answer Incorrect Answer
    D Rotational equilibrium Correct Answer Incorrect Answer

    Solution

    When the vector sum of all torques acting on a system is zero, the object is in rotational equilibrium, meaning it does not rotate.
