Steering Angles Flashcards
When the upper strut mounts on a MacPherson strut vehicle are tilted forward of the lower ball joints, the vehicle has:
a) positive camber
b) negative camber
c) positive caster
d) negative caster
d) negative caster
What type of angle is caster?
a) load bearing
b) directional control
c) tire wearing
d) guide or folowing
b) directional control
The imaginary line drawn through the centre of the upper and lower ball joints on a conventional steering vehicle is known as the:
a) steering axis
b) datum line
c) reference line
d) line of caster
a) steering axis
Caster tends to lean the car into a turn if it is set:
a) with shims
b) toward the front
c) positive
d) negative
d) negative
Camber is measured by comparing the wheel angle to:
a) true vertical
b) caster
c) geometric centre line
d) thrust line
a) true vertical
If the wheel on a vehicle leans inward at the top, the angle produced is called:
a) positive camber
b) negative camber
c) positive caster
d) negative caster
b) negative camber
Excessive camber may cause:
a) tire wear
b) wheel tramp
c) both a and b
d) neither a or b
a) tire wear
Uneven side to side camber may cause:
a) tire wear
b) excessive body roll
c) hard steering
d) the car to pull
d) the car to pull
The inward tilt of the steering axis (viewed from the front) is called:
a) negative camber
b) positive camber
c) negative SAI
d) steering axis inclination
d) steering axis inclination
Included angle in defined as:
a) including caster and camber together
b) steering axis inclination, camber and caster together
c) steering axis inclination and camber
d) point of intersection, true vertical and camber
c) steering axis inclination and camber
When camber is zero (0 degrees), SAI:
a) and included angle will be zero (0 degrees) also
b) and included angle will be the same
c) will be positive
d) will be negative
b) and included angle will be the same
Turning radius is determined by:
a) the amount of toe-out on turns
b) the steering axis
c) how sharp a turn the car can make
d) the angle of the steering arms
d) the angle of the steering arms
Incorrect turning radius may cause:
a) tire squeal
b) tire wear
c) both a and b
d) neither a or b
c) both a and b
When measuring turning radius, if the inside wheel is turned in 20 degrees, the outside wheel should turn:
a) the same to avoid tire wear
b) more
c) less
d) out 18 1/2 degrees
c) less
If turning radius specs are not published:
a) it is not necessary to measure it
b) measurements should be compared side to side
c) the vehicle may not have turning radius
d) use specs from a similar vehicle
b) measurements should be compared side to side
The purpose of the toe angle is to:
a) maximize tire life
b) compensate for any deflection in the steering linkage
c) both a and b
d) neither a or b
c) both a and b
When the vehicle is in motion, ideally the toe setting should be:
a) the same front to rear
b) zero degrees
c) slightly in
d) slightly out
b) zero degrees
Incorrect toe setting may cause:
a) a pull to the side that is most positive
b) instability at high speeds
c) rapid tire wear
d) a pull to the side that is most negative
c) rapid tire wear
Excessive toe-out causes:
a) a pull to the right
b) a pull to the left
c) scuffing wear from outside to inside
d) scuffing wear from inside to outside
d) scuffing wear from inside to outside
The vehicle thrust line is determined by the:
a) rear toe
b) tracking
c) turning radius
d) front toe
a) rear toe
If the thrust line is off to the right the vehicle will:
a) pull to the left
b) pull to the side with the shortest wheelbase
c) dog track
d) all of the above
d) all of the above
The direction the vehicle will travel in is determined by the:
a) thrust line
b) vehicle centre line
c) geometric centre line
d) all of the above
a) thrust line
Moving the top of the MacPherson strut rearward will cause the:
a) caster to move more positive
b) camber to move more negative
c) caster to move more negative
d) camber to move more positive
a) caster to move more positive
Adding a shim with the thickest portion at the top between the rear spindle and axle will cause the:
a) camber to move more positive
b) camber to move more negative
c) toe to move more negative
d) toe to move more positive
a) camber to move more positive
Lengthening a front-mounted strut rod will increase:
a) positive camber
b) positive caster
c) negative camber
d) negative caster
d) negative caster
