Handling

Question 0

Describe some examples of dynamic loads.

Answer 0

Impact due to irregularities in the road.

Manoevering at high speed.

Question 1

What parts make up the static load?

Answer 1

Engine, fuel, passengers, luggage, freight.

Question 2

How does the traction affect the vehicle’s performance?

Answer 2

F=u mg

So acceleration, braking and cornering are all affected by traction.

Question 3

Describe HOW the traction affects vehicle performance.

Answer 3

F=uN

Acts between the wheels and the road.

Question 4

Describe how the static load could be measured.

Answer 4

W=mg

Weight on each wheel =mg/4

Question 5

Describe how increased traction could affect acceleration and braking.

Answer 5

A=F/m
F=umg
A=ug

So increased traction would increase the braking or acceleration force.

Question 6

What forces does a vehicle experience when cornering?

Answer 6

The same vertical forces as usual.

Additional dynamic forces (centripetal) a = v^2/r

Question 7

Describe the equation for cornering force.

Answer 7

F = (mv^2)/r

Should be smaller than or equal to Ft (see circle)

Question 8

What forces must a cornering vehicle have to majntain control?

Answer 8

Enough traction to accelerate towards the center.
Centripetal force (less than traction force)

Question 9

What is the minimum turning radius?

Answer 9

R.min = v^2/ug

Question 10

Describe the circle of traction.

Answer 10

Draw circle.
The axis meets the circle at umg.
This is why loss of traction is so important.
