Questions and Answers

Which of the following is the correct definition of torque?

  • The force that causes an object to rotate in a straight line
  • The tendency of a force to turn or twist an object about an axis of rotation (correct)
  • The force that causes an object to move in a circular path
  • The measure of force that causes an object to accelerate in linear kinematics

    • What is the difference between static and dynamic torque?

  • Static torque produces angular acceleration, while dynamic torque does not
  • Static torque does not produce angular acceleration, while dynamic torque does (correct)
  • Static torque is caused by a force that is not perpendicular to the axis of rotation, while dynamic torque is caused by a force that is perpendicular to the axis of rotation
  • Static torque is caused by a force that is perpendicular to the axis of rotation, while dynamic torque is caused by a force that is not perpendicular to the axis of rotation

    • What is the moment arm or lever arm?

  • The distance between the point of application of force and the axis of rotation (correct)
  • The distance traveled by an object during rotation
  • The force that causes an object to rotate about an axis
  • The tendency of a force to turn or twist an object
