Which of the following eases the driver’s effort in steering the vehicle Correct Answer Positive caster

Explanation:

Caster Angle:

The angle between the kingpin centre and the vertical, in the plane of the wheel, is known as the caster angle. It is also the angular displacement from the vertical axis of the suspension of a steered wheel in a car, measured in a longitudinal direction.

  • Positive caster angle:
    • The caster is called positive when the top of the kingpin axis is inclined to the rear of the wheel.
    • It helps to maintain directional stability and to return wheels to straight ahead after being steered.
  • Negative caster angle:
    • The caster is called negative when the top of the kingpin axis is inclined to the front of the vehicle.
    • Makes it easier to turn a vehicle.

Camber Angle:

Camber is the tilt of the car wheel from the vertical. The tyre life will be maximum when the camber angle will be zero.

  • Positive camber angle:
    • If the tilt of the car wheel is outward, primarily used in the front wheel.
    • It creates more stability and carries more weight.
  • Negative camber angle:
    • If the tilt of the car wheel is inward, primarily used in the rear wheel.
    • It increases corner stability, road shock and component wear.

Toe-in:

  • It is also known as positive toe, refers to front wheels tilting towards the centerline of a vehicle,

Toe-out:

  • It is also known as negative toe, when the rear wheels tilt outwards from a vehicle's centerline.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested courses of action logically follow(s) for pursuing. Statement: Soon you would not need to carry original copies of all vehicle papers like driving licence, vehicle registration certificate, insurance, pollution certificate or the permits issued to commercial vehicles with you. According to a ToI report, the Centre plans to amend Motor Vehicles Rules to make it legal for any citizen to carry digital vehicle documents and simultaneously making it compulsory for traffic police to accept digital version of documents. This means that you would not have to carry physical papers in your vehicle as digital copies of the certificates would be valid.  Courses of action: I. The ministry has proposed installation of FASTags on the front windscreens. FASTag is a device that uses radio frequency identification (RFID) technology for making toll payments directly from the user account.  II. To avail the facility, one has to store all the vehicle documents on the government's cloud-based service DigiLocker and when asked he/she can simply display the stored certificates on a smartphone or any other digital devices. These digital copies can be shared with other departments as identity and address proof.  III. The government has increased the maximum load carrying capacity of heavy vehicles, including trucks, by 20-25 per cent besides scrapping the mandatory annual renewal of fitness certificates for freight carriers. Fitness certificates for trucks would now be renewed in every two years not annually.  Which of the following course/courses of action can be said to be said to be a rudimentary course/courses of action?
