Ideal vehicle balance is reached when: the vehicle is moving forward. the vehicle is moving backward. the vehicle is stationary.
What is ideal vehicle balance?
Vehicle balance refers to the distribution of the vehicle’s weight on all four tires. Ideal balance and tire patch size is only reached when the vehicle is motionless. As soon as acceleration, deceleration, cornering, or a combination of these actions occurs, vehicle balance and weight on the tires change.
What is vehicle balance maintained through?
To manage your vehicle’s balance safely, you must: Keep the suspension and tires in good working order. Practice proper braking, acceleration and turning techniques. Learn how to adjust your driving for adverse roadway conditions.
What type of vision is most strongly affected by fatigue drugs and speed?
Peripheral vision is strongly affected by fatigue, drugs, and speed of travel. It often gives the driver an initial warning of a changing or closed space area.
What type of vision do signs read?
We use our peripheral vision to detect motion and to see changes in shapes and contrast. We use Central Vision to see our target, provide a visual lead, and read signs and signals.
Is the BGE mirror setting always the best?
To correctly adjust the sideview mirrors using the BGE setting, the driver will need to place his/her head against the side window. The BGE mirror is always the best mirror setting. Reference points are the same for all drivers.
What affects vehicle balance?
Slide 21 – Vehicle Balance We know that an object at rest is in balance with the weight of the vehicle distributed equally to all four tires. Movement causes the vehicle to become out of balance and any change in steering, acceleration or braking will affect the vehicle balance.
What is the best steering technique to maintain vehicle balance?
#1.
One-hand steering technique is used when backing or operating vehicle controls such as lights, flashers, and wipers, which need you to reach out from the steering wheel. Placing one hand on the steering wheel can help you maintain vehicle balance and prevent steering reversals and potential injury due to a crash.
When backing up you should use the method?
Reverse is a more powerful gear than drive, so you should use the accelerator pedal carefully, if at all. Otherwise your car will move too fast as shown. To back up, turn to your right so you can see through the back window. Turn your head and body to the right until you can see clearly through the back window.
When managing vehicle speed you should operate at an appropriate speed for?
One rule of thumb to follow (in good driving conditions) is to allow at least one second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds add an additional second. In poor driving conditions (rain, ice, snow, fog, etc.)
What are the three types of vision when driving?
Using your Eyes Effectively
Central vision.Peripheral or side vision.
How can fatigue affect you while driving?
Lack of sleep can make you less alert and affect your coordination, judgement, and reaction time while driving. This is known as cognitive impairment. Studies have shown that going too long without sleep can impair your ability to drive the same way as drinking too much alcohol.
What affects depth perception?
Causes of Poor Depth Perception
Crossed eyes are a sign of strabismus. Another factor is amblyopia or lazy eye, which occurs when the brain function favors one eye. This results in one eye failing to track properly. Trauma to the eye, blurry vision and nerve problems can also cause poor depth perception.
What vision allows you to focus and read?
Central vision is when our eyes focus straight ahead, allowing us to drive, read, and see details sharply. Central vision only covers about three degrees of our visual field, but it allows us to make very important judgments like estimating distance and understanding details in the path ahead.
How is car stability calculated?
A vehicle’s SSF is calculated using the formula SSF=T/2H, where T is the “track width” of the vehicle and H is the “height of the center of gravity” of the vehicle. The track width is the distance between the centers of the right and left tires along the axle.
