Machine Kinematics Multiple Choice Questions on “Steering Gear Mechanism”.
1. The tilting of the front wheels away from the vertical is called
a) caster
b) camber
c) toe-in
d) toe-out
Answer: b
Clarification: The angle between the vertical line from the centre point of the tyre and the central line of the tyre is known as the camber angle.
2. In the steering gear, a gear sector or toothed roller is meshed with a
a) ball bearing
b) roller bearing
c) worm
d) steering wheel
Answer: c
Clarification: A rotary valve power steering gear for the integral system uses recirculating ball-type worm and wheel steering gear.
3. The only service that a steering linkage normally requires is
a) tie-rod adjustment
b) lubrication
c) ball-joint replacement
d) none of the mentioned
Answer: a
Clarification: In the linkage-type power steering system, the power cylinder is not a part of the steering system. Instead, the power cylinder is fitted into the steering linkage.
4. Caster action on the front wheels of a vehicle will
a) make it easier for the driver to take corners
b) help reduce the load on the king-pins
c) automatically achieve the straight wheel position
d) none of the mentioned
Answer: c
Clarification: Negative caster produces directional stability to the vehicle keeping the wheel position straight.
5. Too much toe-in will be noticed by
a) excessive tyre wear because of taking corners
b) steering wander
c) feathering of tyres
d) light steering
Answer: a
Clarification: The toe-in ensures parallel rolling of the front wheels. It stabalises steering and prevents side slipping and excessive wear of the tyres.
6. Hard steering is a result of
a) very loose steering linkage
b) worn out steering linkage
c) too loose front wheel bearings
d) incorrect lubricant
Answer: d
Clarification: Hard steering is caused because of the following reasons:
a) incorrect lubricant
b) broken or bent steering arms or knuckles
c) too tight spherical ball joints
d) insufficient lubricant
e) low or uneven pressure.
7. Excessive play or looseness in the steering system is caused by
a) worn out front wheel bearings
b) broken or bent steering arms or knuckles
c) too tight spherical ball joints
d) insufficient lubricant
Answer: a
Clarification: Excessive play or looseness in the steering system is the result of
a) very loose steering linkage
b) worn out steering linkage
c) too loose front wheel bearings
d) worn out front wheel bearings
e) loose steering gear flexible coupling
f) worn out steering gear flexible coupling.
8. Erratic steering is caused due to
a) worn out brake lining
b) broken or bent steering arms or knuckles
c) too tight spherical ball joints
d) insufficient lubricant
Answer: a
Clarification: It is caused due to following reasons
a) worn out brake lining
b) brake lining choked with oil
c) brake lining choked with brake fluid.
9. Wheel wobbles occur due to
a) inoperative stabilizer
b) wheel out of balance
c) bent kin-pin
d) bent steering knuckle
Answer: b
Clarification: It is caused due to following reasons
a) wheel out of balance
b) worn joints in assembly
c) loose wheel bearing.
10. Wheel wobbling can be fixed by
a) adjusting and repairing it
b) repairing the stabilizer
c) replacing kin-pin
d) replacing brake lining
Answer: a
Clarification: It can be fixed by the following remedies
a) adjusting and repairing it
b) balancing wheels
c) adjusting bearings.
11. Hard steering can be fixed by
a) replacing the bent or broken parts
b) replacing worn out parts
c) tightening the loose bearings
d) none of the mentioned
Answer: a
Clarification: It can be fixed by the following remedies
a) inflate the tyres to correct pressure
b) replace all tight ball joints
c) replacing the bent or broken parts.
12. Erratic steering can be adjusted by
a) replacing worn out parts
b) replacing the brake lining
c) tightening the loose bearings
d) none of the mentioned
Answer: b
Clarification: It can be fixed by the following remedies
a) replacing the brake lining
b) locating and removing the cause for choke
c) removing the cause for choke due to the brake fluid.
13. Excessive play can be fixed by
a) replacing the bent or broken parts
b) replacing the brake lining
c) tightening the loose bearings
d) none of the mentioned
Answer: c
Clarification: It can be fixed by the following remedies
a) replacing worn out parts
b) replacing worn out couplings
c) tightening the loose bearings.
