Answer

Brief Explanations:

  1. The steering mechanism in a vehicle is for ensuring the vehicle turns without skidding.
  2. For a wheel to roll perfectly, the velocity at the contact - point must be zero.
  3. Rack and pinion is the most commonly used steering mechanism in modern vehicles.
  4. Electric power steering makes the steering action effortless for the driver.
  5. If the electric motor fails in power - steering, the steering works normally (but without the power - assist).
  6. For a perfect turn, the left and right wheels must turn at different angles.
  7. The role of the ECU in power steering is to manage the torque supplied to the steering column.

  3. b. Rack and pinion
  4. c. By making the steering action effortless
  5. d. The steering works normally
  6. b. They must turn at different angles
  7. b. To manage the torque supplied to the steering column
